I swear if I was not the one that posted this I would take the chance to make a dad joke and say "I don't think the name "A.C.E of Hearts consisting of 3 members named Ava, Claire and Eliza" is very efficient but you do you." and I'm not sure how to feel about it.
it's basically a joke about how there's no specific indication that the group's name ended, thus extending the name to the period at the end of the sentence. It's a silly joke like a dad joke.
