I think I understand the logic, but just to be sure here are some examples.

1. If someone throws a brick at Touma, he can't stop it with his powers.

2. If someone used any sort of supernatural ability (be it magic or any other type) to continuously push the brick or make the brick go faster, Touma can stop it with his powers.

3. If someone with wind based powers uses a gale to blast a brick at Touma, he can't stop it with his powers.
