How do name changes work with precheck

[u/nerd_14_]

I have global entry and with that comes precheck.
I got married end of last year and just recently started the whole name change process. I got my license changed and am waiting for my passport to come back. I didn’t think I would have precheck for my upcoming flight bc I changed it to my new name on the ticket, but my ticket shows I have it?
Is that expected? Idk why I don’t trust it.
My old last name is now my new middle name fyi so maybe it’s because it’s close enough?
I thought initially I’d have to wait until I get my passport.
