One from the mound?

I'm surprised that in my 30+ years of umpiring, this never came up. I guess nobody did this move and then threw the ball into DBT.

I haven't done Fed in a long time. Is their rule different?

No, we didn't explain this appropriately. I apologize.

My reference to disengage vs stepping off was to discussions with coaches about moves directly to first.

In OBR the 3-1 move you are referring to must include separation from the rubber. This is why the pitcher may, and most often does, fake the throw to first.
