if my device has logged into someones gmail, will it still show on device list after being factory reset?

someone that i was friends with in a phone game decided he hates me and recently factory reset my phone and my tablet remotely through a shared gmail account. that part is over and done, but we shared more than one gmail account and i want to prevent him from doing it to me again. I would think that when my devices were reset it would remove them from all accounts that they were logged into, but wanted to be sure that he will not still see my devices logged in on any of the shared accounts. i have not added those accounts to either device again, the only account added is my private account.
