This is a tough one - I don't think Jon intended to hint at alcohol problems, and may have been misquoted or taken out of context, but he did make a comment about it being the same situation as before, or "we've been through this before", which most people read as being about RS and alcohol etc.
But as I said, that's not really JBJ's fault, or at least isn't anything more than a careless response.
EDIT: Jon was intending to just talk about Phil X helping out again!
No biggie.
