A320 Ferry flight with gear down

Heya guys.
In the FCOM there is a procedure for special operation flight with the gear down.
It says about the switch on 188VU in the avionics bay to change the VMO to 235knots (from standard 280kt VLE).
This is fair enough because on a ferry flight there is a long time with the gear down so this reduction in VMO is to reduce fatigue.
My question is regarding the protections. Does this switch modify the protections so that the overspeed protection kicks in around 240? or does the barbers pole show 235kt but the overspeed remains at 280kt (VLE gear down)?
