Yes, this is true for most parts of the parser and is a common and long-standing way to avoid issues with special characters and parsing. There's no chance of this ever changing. Make (almost) always does word separation BEFORE it does expansion. I actually can't think of a place where this is not true but it's possible I'm forgetting something.
