Confirmable Suite Upgrades will be applicable for one room upgrade to an entry-level suite or premium room where a suite is not available.

My reading of that is it only applies to when you book a lower level room and it’s an upgrade to the lowest level suite and not from a lower level suite to a higher one.

But as Northern Lass says says no harm in calling and asking,

Note the AMB upgrade won’t stack on top of the CSU upgrade,
