No, the jacks collapse as the aerodynamic backloads from the rotor overpower the hydraulics.
Since the highest aero loads are on the retreating side, aft of the lateral position, it displays the same symptoms as retreating blade stall - ie a roll to the right and a pitch nose up.
Just like RBS, it is encountered at high AUM/high speed/harsh manoeuvring/ham-fisted piloting combinations.
On the Gazelle, it was demonstrated in a dive to VNE at MPS (168 kts with about 14.5 degrees of pitch) and still required a hard pull to get it in.
The other demo was in a hard left turn with a hard pull - never done in a right turn as you could end up inverted.
