Gliding "paused"

Having seen this conversation:

I can well imagine that the following could easily have occurred…

why is it so hard for the two organisation overseen by the same sponsor have such a different outlook on activities and risk?

is it anyone wonder there is “one book” but 900 (Squadron) ways of interpreting it if there is such a vast chasm between what is considered a permitted activity between two similar organisations (the ATC and ACF)?
