Er... maybe I'm being dense, but doesn't the second paragraph describe exactly the same thing as the first, just in a more complicated way? (1): touching yourself is predictable, so only unpredictable touches cause tickling; (2): when you touch yourself, there is an inhibition mechanism that prevents your own touches from tickling you, so only unpredictable touches cause tickling. Both phrases actually state that your brain, your nervous system, whatever, can differentiate between your own touches and someone else's (or even touching inanimate objects, think spiderwebs) and has a way to ignore your own.
