This is correct. "Third Spell: Mens (Mind)"  says as much, and it pops up occasionally in storylines. As you say, nothing but the actions are recorded. No residual thoughts or inclinations are picked up by the band unless the memory comes from the person its coppied from.

"And, like with a mask, you cannot wear your own mens but you can update it by putting it back on again, so that it will start "remembering" all the stuff that you did after making it. You can also give yourself its memories. You lend your mens to a friend who needed to use your brain on a math quiz, and when he gave it back you put it on. When you woke, you "remembered" going to his class and sitting in his desk and taking the math quiz; in fact, you remembered almost everything up to the moment that sat down to pull it off again. The odd part was that, although you remembered doing things, you didn't remember any thoughts or feelings. You only remembered the actions."
