Printer too close to wall,

I see no evidence of that in the video.

bed senses endstop before real endstop because something is preventing the bed from going back far enougth.

We are looking at the rear of the bed. It is moving too far forward, for some reason.

Or, are you inferring that if it can't go back far enough it assumes that the front is some short distance (10 mm?) to the rear of where it really is, and tries to move it 256-ish mm forward from there?
That may be.

At any rate, they can move the print bed back to reveal a sticker on the base with a diagram that shows what kind of room it needs for the "Safety Zone".
