What will a guy think if you block him on Snapchat after accepting his friend request?

A friend had taken me down on Instagram and WhatsApp for reasons I’m still unsure of. Maybe he got a girlfriend that he didn’t want to expose. I don't know. Anyway I thought this was rude so I had actually already deleted him on Snapchat. The other day I had accepted his friend request (happens when they haven’t unadded you but you deleted them) just to check what’s going on and if he had messaged me there. Then I blocked him so I was removed from his side as well. I don't know if he got notified but he might have seen it if he checked the list. What would he make of it?
