Message is open. The orifice leading to the check valve and to the bleed nipple, is on the conical seat of the bleeder, when that seat is tightened against the corresponding seat in the caliper, that orifice is completely closed off, just like the stock bleeder. Fluid cannot get to the check valve if the orifice is blocked off. The only way the bleeder can leak is if it is not completely seated against the caliper.

Now we do find that when installing new speedbleeders, you want to pump the brakes/clutch and check that the bleeders are fully seated. With the fresh thread compound on the threads, it may feel like it has seated when it is not. I've not had any problems on any speedbleeders I installed.
