Only problem with that logic is that any buggered line, dryer, fitting, oring, sensor, evap unit, etc. would continue to leak when the system is filled with N2, which is appears not to be doing; the only thing that would not leak would be the compressor because it is not running. Often the compressor seals leak only when a low area on the shaft passes the damaged seal arear while the unit is turning, but with nitrogen in the system preventing the unit from running, the shaft is not moving. Boosting the pressure beyond the normal running pressures would also tend to "push" the compressor seals more than normal, also slowing or stopping the leaks.
