When do I need 1 or 2 MOSFETS for my load switch on VBUS?

Everything is linked to the MOSFET's body diode that can let current flow if there is a voltage or a residual voltage.
For example, in a provider path for DRP applications, you always need two MOSFETs as on one side you have a Source and on the other side you have the VBUS voltage coming from the cable
