I'm not a DMU man, so this is conjecture based on other stock.
I'm guessing that the tank charges gently whilst the train idles in the station and so is fully topped-up by the time the train is ready to leave. When the train revs up the compressor runs faster but its output isn't needed straight away, therefore the excess blows off.
Maybe.
(We don't have this situation on EMUs. The compressor(s) run only when they sense the MRT pressure drop).
