I have no experience with a T-Series for the 1911 but this is my thought as well. Releasing the paddle likely puts the thumb underneath the safety and will require a repositioning to deactivate.
Thumb repositioning is required with the Glock as well. As gripped and released, my thumb is above the mag release and is more or less level with the vertical groove in the Glock grip. I have to lift my thumb to make room for my support hand. In practice I haven't found this to be an impediment or distraction. But I'm only moving the thumb up rather than up and around as would be required with a 1911.
