Beagle is VERY wide of the mark, in my years of instructing (refresher students and standardising instructors) on RAF jets, never heard it said that a victory or aileron roll is a particularly dangerous manoeuvre. They have a technique which makes them a simple and safe aerobatic. Raise the nose to a suitable angle, apply (full) aileron, a touch of rudder perhaps, wait for wings level and fly away! Without any elevator input the nose WILL be lower than on entry, and that determines the pitch attitude to be used at entry.
As for needing full aft stick to stop the descent, that would produce a possibly severe G stall, to say that suggests a serious misunderstanding of control and stability. Pulling to just nibble at the buffet was the technique to get the best pitch rate from the JP.
And air displays are not flown by "Bloggs" .
From what I saw in that video , a perfectly safe roll was seriously mishandled, period.
The exact height of the roll is irrelevant, it was done very low, and too much height was lost in the roll, it was not difficult to roll the JP without any height loss and there was enough control authority to push to minus 2.5 g when inverted, but with a time limit imposed by fuel recuperator capacity.
