When you bleed brakes, you need to pump the brakes several times before opening the bleeder. On a clutch, once is enough. Also, as long as the clutch pedal is not released until the bleeder is tightened, no air will enter the system. If the clutch pedal is released with the bleeder open, it will then draw air into the system.
Your idea with having the fluid in a jar so it cannot draw air back in will work too.
