Well I hear or probably even read from wiki comments that walkers proc the mastery that gives you gold when you auto attack enemy champion.

That being said, it might be that walker's attack is somehow registered as Yorick's on AA, but it does not actually proc life steal. So it is like it would proc attack with 0 AD. The attack is done, but no damage to lifesteal from.

TL;DR It most likely is just the walkers being weird.
