Though it doesn't make sense that it'd be noticed after already loaded and the plane pushed back.

Hard to imagine they would remove a whole can of bags that were supposed to be on that flight. Especially a domestic flight that likely wasn't heavy on freight/mail, where w&b could be an issue and there is no PPBM. The only other thing I can think of is that maybe they loaded a can of bags that were for a different flight onto that plane, then realized it when those bags were missing for their correct flight. That's something you certainly bring a plane back for, though I've never heard of something like that happening, and itd be a colossal screwup for sure. That's only my best guess, though.
