I'm still in the learning process. Like you, I anticipate when I have to clip out by remembering: "hey you are clipped, remember to clip out the right foot".
It isn't so much that, but it is simply part of my stopping process. I don't generally slow down enough if I don't unclip a little early. Don't ask me why, but there you go. I can still stop, it just isn't very graceful & I then get tire marks on my leg
