Person blocked me but I can see his picture ?

[no]

Hello!
My ex blocked my on facebook (immature I know sigh) and of course after that I couldn't see his picture or anything, but now, today, when I was going to answer on a new comment of one my pictures that he had once commented on I could see both his picture, plus his name was linked to his profile just as usual ... but I couldn't enter it, what does this mean?? Like, since I cannot enter his profile I must still be blocked but then why can I all of a sudden see his picture?
(Don't ask me why I care ugh)
he have not deactivated his account though, I know that

Its Possible He May have Unblocked you and Than Deactivated His Account
