He probably did for a brief moment, but when it came down to using them again he had the "yips."
It's kind of like if you were to suffer a sprang. In the time it takes before you can get up, you've "lost" the ability to walk/run/jump/ectetc. When you've finally gotten back on your feet, it will hurt and you'll likely limp (I always do). That's when the "yips" starts developing.
