Question about word choice in this sentence: "Although he’ll be moving into a postdoctoral position soon, he's going to miss John."

In a comment, John Lawler wrote:

It isn't clear whether he or John is moving, and it isn't clear why although would be used. And people could say moving into a postdoctoral position, but probably wouldn't, since quite often you just move up to a postdoc where you are. Moving where you live is a separate issue. If you want to mention the postdoc, do it in a different clause from the moving.
