>So a butcher, doing butchery, stops doing butchery the second the animal has no more useable meat?

The moment it's processed, yes, the butchering is completed.

>Do they have to hand the meat over to the meat cutter after that so they can do the meat cutting to get the different cuts, I guess?

No, you see because that is a synonymy of butchery. The process is still incomplete if the meat isn't cut. Cutting meat is butchering it. So the process is only finished once all the meat has been cut. The one, singular, only process happening is finished once the processing of the carcass is done. There can't be two processes happening, unless perhaps there are two butchers fighting to process the same meat. One butcher butchers a carcass, and all the butchering of that carcass is one instance of butchery, in much the same way 9 innings are not 9 consecutive instances of different games of baseball.

>Because a butcher doing butchery definitely wouldn’t be the one to do that. That’s not butchery as we’ve established.

Nobody said this but you. I'd almost think you don't know what butchering even is, except we couldn't have made it this far if that were the case.
