Would he still show up under her friends list?

i was taking to a old teacher from high school on facebook
she was telling me that a past student of hers would hit on her so she blocked him.

i was curious so i looked around he is still on her friends list & she is on his friends list.

i thought if you blocked someone on facebook they would be removed from any friends list.

Would he still show up under her friends list?
