He did not double post.
Double posting is posting the same topic/post more than once.

Bumping is posting to the topic in order for it to get to the top of the "Recent Posts" and to get it to the top of the post list in its original forum. However, bumping a mere 8 minutes after the original is considered spam. On most forums, if bumping is allowed, its usually once every day, or so.
