can u get achievements during dev commentary in portal 2?

[Teletha]

there are 2 sites saying different here:

 

Take notice that the test subject can't get any achievement while testing in developer commentary mode.

 To counter this, achievements cannot be unlocked whilst in commentary mode (except in the case of Portal 2's Single Player), as it makes the game easier. Activating a commentary node will not stop music or sounds.

do i suppose the portal wiki is more correct?
