I think that while Baam has the power of an Irregular from outside the Tower, Rachel is a person from inside the Tower who went outside (she came from above where Baam was). Thus, she is not a proper Irregular and does not have the power Baam does, but she is still able to bend the rules of the Tower and act outside the predictions of Guides.

Just how dangerous she is remains to be seen though...
