I took time to read all the highlights of the links that you provided because I am so curious about this issue. I'm not sure what is your interpretation but for me, it's the same as what most people say here: PR sponsor MUST reside in Canada, short trips outside Canada are tolerable depending on the visa officer.

"The appellant was engaged to the applicant on 14 July 2007, and landed in Canada on 11 September 2007. After landing, she married the applicant via proxy marriage on 25 November 2007. A sponsorship application was submitted on 4 June 2008, an interview took place on 23 April 2009 and a refusal letter was issued on 28 April 2009. On 23 November 2009, following the refusal of the application, the appellant left Canada and travelled to Pakistan. She has been residing in Pakistan since that time and has not returned to visit Canada. The appellant’s permanent residence card expires on 1 October 2012. The appellant expects the birth of her first child on October 14, 2012.
Section 133 of the IRPR states:
133.(1) Requirements for sponsor -- A sponsorship application shall only be approved by an officer if, on the day on which the application was filed and from that day until the day a decision is made with respect to the application, there is evidence that the sponsor
(a) is a sponsor as described in section 130;
130.(1) Sponsor -- Subject to subsection (2), a sponsor, for the purpose of sponsoring a foreign national who makes an application for a permanent resident visa as a member of the family class or an application to remain in Canada as a member of the spouse or common-law partner in Canada class under subsection 13(1) of the Act, must be a Canadian citizen or permanent resident who
(a) is at least 18 years of age;
(b) resides in Canada; and
(c) has filed a sponsorship application in respect of a member of the family class or the spouse or common-law partner in Canada class in accordance with section 10."
ME: In this case, they are refused based on their marriage. Yes, the sponsor was questioned from being out of Canada because he left Nov2009 and did not return until (approximately) 2012.

[6] The appellant married the applicant during a trip to China that lasted from August 31, 2006 until April 11, 2007.[7] On September 21, 2007, he returned to China to wind up his real estate company. In December 2007, his plans to sell his business to the Communication Bank of China fell through. He decided to remain in China to be able to celebrate the Chinese New Year in February with his wife. He then remained in China in order to accompany his wife to her interview which took place on April 15, 2008.[8] He returned to Canada later in April 2008.
ME: In this case, the sponsor was out of Canada for 6months or more. Thus, it cannot be considered as vacation.

Analysis: However, it appears that, at the time he filed his applications, the appellant was pretending to be living in Canada. Based on his entry/exit documentation to and from Canada,[6] it appears that the appellant spends most of his time in France. His visits to Canada are quite brief.
ME: In this case, the sponsor is living in France, not in Canada.

[3] The appellant was not a permanent resident when he filed the application to sponsor his spouse. He became a permanent resident on June 11, 2008, and then immediately left Canada. The appellant is currently in the United States. On March 24, 2009, he filed an application to sponsor his spouse. Unfortunately, at that time, he was not a permanent resident in Canada, but rather a resident of the United States. Consequently, pursuant to paragraphs 130(1)(a) and 130(1)(b), he does not meet the conditions for being considered a sponsor under the Immigration and Refugee Protection Act (the Act). As Ms. Raymond explained, the only exception to this rule would be if he were a Canadian citizen, which unfortunately is not the case.
ME: In this case, the sponsor is a resident of US, not Canada.
