You are most welcome, i assume submitted all details of your own work permit i.e. employer details, NOC etc.
I don't think in general you should worry since this is a clear cut detail. However, strange enough i have seen at least one case, in which husband was already in Canada on a post doc, applied for SOWP for his wife and trv for child, and received refusal stating bla bla that you do not qualify for SOWP due to this section of immigration. Apparently CIC failed to recognize that SHE WAS SPOUSE OF A WORK PERMIT HOLDER in NOC A, although the applicant had VERY CLEARLY stated that and attached his docs along.
Then they reapplied with further clearance and i am yet to hear of further input. Some how they got dumb enough people who make mistakes in CIC and unfortunately there is no way to hold them accountable.
Having said all that, since they specifically asked you and you explained that clearly and i assume you have submitted evidence along, you are very less likely to face any such situation.
If i were you, i would try to be more explicit by submitting my job offer, salary slips, even bank statement, Copy of actual work permit and visa just to make sure they understand the situation and have enough proof to stand by.
