Question on weapon loadouts and AI

[clownagent]

In the ruleset it seems to be possible to give several weapons to an alien (with the itemSets keyword). For example a blaster launcher AND a plasma rifle.

In the current state of the game would the alien use both weapons on the battlescape (maybe alternating)? How does the AI "decide" which weapon to use?

I tried this: I gave the aliens a flame clip and a normal clip for a certain weapon and they used the first one in the equipment list first. I guess it would be the same for the weapons, once the first one is empty they will , most likely, use the second. But I am NOT 100% sure.
