Could be for a number of reasons that have nothing to do with him potentially staying in office.

My prediction is he is trolling Joe and making it so he will spend his first 100 days getting less done trying to figure out which of these EOs he has to undo and which ones will make him look retarded for overturning.

Trump being Trump.

If Trump truly is leaving, it's basically a nose-thumb at Biden - enact a bunch of things that may look good, they get repealed, and if something goes wrong because they were repealed Trump can go "See, look at what that idiot did!"

Very good question.

The retard will just undo whatever Trump does now. Waste of time.

They are all useless and a smoke screen unless he makes sniffing children illegal.
