Owner/Dog With Multiple Accounts?

I rarely use Rover now that I have more hours at my other job but I still have the app and I try to keep my calendar updated, but somehow I missed a notification from 22 days ago where a guy asked me to dogsit for a week (starting yesterday). I never saw a notification on my phone, so today when I got a new notification about housesitting I looked at my inbox and realized that both the new request and the old request were from the same guy (same photos), but with different names (for both owner and dog).

Has this happened to anyone before? I know people forget passwords, but 22 days apart seems like a short amount of time to create a second account in (and I feel like Rover would have password recovery stuff set up anyway). And why ask me twice, especially if I didn't respond the first time (oops).

I'm mildly creeped out but maybe I'm overreacting.
