I've always heard the air gap in a water heater tank is what caused the valve to leak. Burp the valve and no more leak. At least, mine works that way.
Most likely what you're doing is just re-seating the valve. Unless you hold the P/T valve open until a solid stream of water comes out, you still have some air bubble in there.
We did the same thing in a steam plant. If a relief valve was jiggling a little during startup, we'd lift the seat and let it slam back down to stop the dribble.
Here's how it works.
