When you are in your good spec, you use AP items right away (some people at least), you get it, you use it, you get it, you use it... You developp the reflex of doing it after so much repetitions.
Potions, flasks or runes, you never use them right away, you can't developp this "muscle memory" kinda thing, you're not conditionned, with AP items if you use them right after you get them every time, the moment you get one with the wrong spec, you'll still use it because you have the habit to do it.
