I will say that if the information that this flight was higher than a previous arrival is correct, your suggestion that glide slope was never captured and the flight remained in a VS mode, is quite possible. This wouldn't be the first time recalling an Air Europa charter landing in Katowice that 'landed' short of the runway.
Additionally, a high descent rate from either a false glideslope or selected VS would result in low thrust and high inertia that, once GPWS Mode 1/2 became active, could result in an unexpected state from which a go-around would be more challenging.
All that said, I would hope either scenario would be trapped much earlier at the stabilisation 'gates', but a less-than-fresh crew is always a threat in any operation.
