They can extend those outside the body of the coral to digest things like food or neighboring corals. Sometimes see them if the outside of the flesh gets injured too. Not all corals produce sweeper stinging tentacles to fight neighboring corals. Some use these filaments. Acan echinata or orange 'Lobo' are good examples.. very very aggressive with them.

If it were these, wouldn't they be coming from the top/front of the coral, not the base?

Normally yes. When they pop out on the outside of the skeleton like that it’s usually in response to irritation or possibly a little tissue damage imo.
