Accidentally liked someone's Instagram post then blocked them. Would they still be notified?

Help !

Hi everyone , I'm so sorry if this sounds pathetic.
I was on Instagram checking to see if this man I've been chatting to and have met up with had uploaded any photos of trip he said he was going on ( I hadn't heard from him for several days and was starting to worry that something had happened to him. I suffer really badly with anxiety.) And I accidentally liked his photo , quickly unliked it then after a few minutes decided to block him and change my username out of panic.
We don't follow each other and he doesn't know that I know about his Instagram account 🙈. I only found it when I did a reverse image search when we first started chatting ages ago and before meeting up ( just to make sure he wasn't catfishing me.)
My question is would he still have gotten a push notification saying I liked his post and if so would it of shown my old username , or would it be my new one?
Thank you 🙁

I ended up explaining to him that it was a accident. Not even sure if he's got push notifications on but I decided to tell him anyway.
