Maybe Tom's power is limited because of the fact that he does not in a way belong. This goes back to the letter that talked about different planes of existence. It could just be because the plane of existence that Tom is from only overlaps with the forest and that makes his power limited to the forest. It could also be as Alatar stated and he set his own boundaries or it could be both.
