Why is it confusing that a mage can learn several types of magic?

With Laxus the problem is that the two are so similar and thus hard to tell apart, but for Mira that's not the case.

Transformation is just like wrapping yourself in an illusion (except the size changes too), but gives no power-ups, which clearly sets it apart from Take-Over. And sleep is obviously something completely different.

Apart from that she's the only one we've ever seen to use Take-Over: Satan Soul, while we've several (you could even say many) others use Transformation.
