That makes perfect sense, but...in this case, the person submitted an Outland application while being out of status. While the worse case scenario would be that she is removed from Canada and issued an Exclusion Order, the fundamental question is...how likely is that to happen? This is probably why she decided to withdraw it and submit an Inland application instead. Since we haven't yet heard what she was told by CBSA, we just have to wait...and wait...and wait.
Hopefully, they told her to cancel the request to withdraw her application and that she'd [likely] be allowed to stay.
(crossing fingers).
