Exactly. Why else does Xemnas looks like Terra? Remember, Terranort done the research with Ansem the Wise, and Master Xehanorts body became Unknown before Terranort split into two. (Ansem, Seeker of Darkness, his heart, and Xemnas, his body)

Here's this in a canonical order.

Master Xehanort heart joins with Terras'
Master Xehanort becomes Terranort.
Master Xehanort body disappears, becoming Unknown.
-Time Skip off Last Story-
Terranort joins Ansem the Wise.
Terranort delved deep into the darkness.
Becomes both Ansem and Xemnas.

And, if Master Xehanort IS Xemnas, then answer me this? Why does Xemnas look like Terra? Terras' body fits Xemnas body, and Unknown is less bulky than either of them, like Master Xehanort (except looking like Xehanorts younger self). Remember, the Nobody looks a lot like their whole being. Braig and Xigbar, Dilan and Xaldin, etc.

Makes perfect sense. Remember, read carefully.
