Just a way around the issue without leaving bags behind IMO. The plane wasn't out of limits weight wise, but in an aft CG cargo wise.
It was the FAs comment that still confuses me though ... why would passengers be kicked off if they didn't move the bags up versus just leaving some of the bags behind to follow. (again, NOT something I'd want to have happen to my bag, but UAX has been known to do this w/o consideration for the impact to the passenger)
