I'd have to disagree with Lynne on this one. If you're inverted at 100 fsw the last thing you want to do it hit your BC inflator. You're unside down but not positively buoyant unless you add to the problem and now hit your BC inflator button.
Oh, I didn't mean to do this AT DEPTH! I meant that, once you have arrived at the surface and find yourself hanging from your feet (which is apparently what happened to this lady) the quickest way to right yourself is to inflate your BC. Apparently much of her actual trouble occurred as a result of finding herself in this situation and concluding she had to shed her gear to solve it.
