vsthe plug blew out a caused an air leak. Thankfully this occurred after the dive was over or I would have had a bad air leak.
You could completely unscrew the SWIFT from your first stage underwater and it would still take like 20 minutes for an AL80 to drain. The HP ports have flow limiters (tiny exit holes).my dive partner did notice a small trickle of bubbles coming from the vent hole but not a major air loss by any means.
