B737 VS. A320 PTU

Joe describes how the PTU in the 737NG varies from the A320. While the Airbus 320 PTU activates for a 500psi pressure difference, the 737 activates for a more specific: loss of pressure on the B system engine driven pump.

What happens when there is loss/leakage of hydraulic reservoir of System B, will PTU inhibit in 737 in case ?

Hey Joe awesome video. Why does the Green 320 system remain lower quantity at cruise? Is that because it is holding the landing gear up?
