Human Sim getting impressively far in Vampire aspiration

I have a Sim who was born a vampire but decides he wants to leave that life behind him and takes the cure. He had the Good Vampire aspiration, so he fulfilled the requirement of being a vampire for the first tier.

And turns out he can make it all the way to the third tier without needing to be a vampire. It's pretty amusing seeing the pop up that my human Sim has "successfully resisted drinking deeply" for X days in a row.

I'm sure others have noticed this before, but it made for easy satisfaction points and was just plain fun for me.
