Three ways. It could do a join to the cur table and old table, or to recent changes.
Special:Watchlist joins only to cur; there are two ways to optimize the join/sort operation (starting from watchlist, or starting from cur).
If the function did something else than what it does, then it might have many different ways of doing it, of course.
