Guessing that's a typo. I've seen no change in the policy myself in my most recent stays, including just a few days ago.
The other scenario is that this is how they prefer to communicate it because technically, suite upgrades for CC members are at the hotel's discretion and not guaranteed as part of the program - but almost always come through. Not 100% though. Hence why they may not want to advertise it as such.
Better to under promise and over deliver...
