No, no. That's not it. The wings are something extra he gets that can be used for flying, defense or as a very deadly weapon. They are probably connected to something of greater significance, but that's still unexplored. What powers the wings is also still unclear, but he uses them instinctevly... in other words, he doesn't need his high brain function to use them, as opposed to regular esper powers.
If you're talking about that other power
then he learns to use it with his normal esper ability.
