I'm guessing he didn't have one?
Homing dash is when you push forward after a dust attack. It usually lets you dash forward so you can do some wall bounce combos in the corner.
I'm guessing Pot didn't have one since he doesn't have a dash in game. Bedman's dash (and thus his homing dash) isn't cancelable since it is a parry rather than real dash, so they gave him a homing dash option too by letting you cancel it.
