The question was later reopened at 08:57

Four hours just about hits the top of the ceiling fan there for the grace period in posting an answer on a question recently closed. Any longer and you'll be lockblocked.
It's there to allow slow pokes the time to finish off what they were answering on the off chance that the question will later be reopened.
