Multi-Power Attack or Two Weapon Fighting

[Vanguard]

Steve,

 

Been through the FAQ and I *think* I might have figured it out on my own but I've always been a confirmation type of guy.

 

Here's the scoop:

I've got a character that has twin Elbow Blades (ala the Guyver). Now, I've purchased these blades twice, one for each elbow and they are both in an EC. The character also has Two Weapon Fighting (HTH).

 

Now, here's the question: When he attacks with both of these, is he considered to be doing a Multi-Power attack or a Two Weapon attack or does it depend on who/how he's attacking?

If they're separate slots in an EC, the character can't use them to make multiple-Power attacks together (5E 204). So he'd have to use TWF, or call it the special effect of a Sweep, or the like.
