Strange when I read Clare's report on the changes it read that thats exactly why it was changed.
The valve drill was changed because it more closely follows the sequence employed (as taught by GUE) on a real shut down (which ultimately is the point of the drill), i.e. it is unrealistic to ever shut off the left post whilst breathing it and have to switch to the long hose.
Reducing the likelihood of accidentally turning off all your gas or worrying about getting back to the long hose might be added benefits but AIUI not the point of the change.
