1 and 2: blank stare. I got nuttin. 3. In addition to what others have suggested looking into (and I second the question of does he know how to shift friction gears? Simple test: does it ghost shift when you ride it? If not, teach him how to shift), there is a twist tensioner for most thumb levers on the lever itself, usually with a flip out "handle." If this comes loose (and it can with time) it can ghost shift.
If that fails, I had great luck curing my ghost shifting by reversing the pulleys on my derailure. The theory being that the top pulley has unnecessary play for friction shifting (but that indexed shifting requires to be "reliable") The bottom pully does not have this play, so reversing them cures the ghost shifting.
