If you learn to feel the pressure of the cam, you will always know you have not passed it and can immediately snap the throttle closed. I’ve had hot starts and you need to be quick! Some weren’t ‘real’ though and were due to faulty ITT compensators.
As you know when ever there is a new Tech pilot/chief pilot, etc he or she has to introduce their own procedures which are not always based on fact or good practice. The company I was with also had this same idea that when the starter is engaged there might be so much draw on the batteries that there would not be enough left to actuate the idle stop release. So they said roll past idle stop, back to the stop, hit the release and roll back just slightly over the cam so if it goes hot you could just close the throttle. Not saying a good idea or bad, just that if you wanted to comply with SOP's sometimes you had to do stuff that you may or may not have agreed with.
