Is there some pressure forcing fluid into the reservoir at the same time?
If so, you shouldn't have to worry. Also, make sure you just crack the bleeder ever so slightly. Just open it enough to let it start dripping a fine line. It shouldn't be pouring out like water in a faucet.
No force but the master cylinder. I planned on doing a pedal pump bleed
and I wasn't sure if this Lisle tool was accurately described as a "one man bleeder". It was less than $6 and I needed something small to put my Autohausaz order over $50, so I figured I'd take a look at it.
The ways to one man bleed are using either pressure via a forced bleeding system (VAG tool 5234 is what I use here at the job) or using vacuum....most hand vacuum pumps sold nowadays include a self brake bleeding kit.

If you can't afford a Motive bleeder (which I highly recommend)...
Sears sells a vacuum bleeder that is slightly cheaper, but somewhat of a pain in the *** to use. Instead of forcing fluid through the system by pushing it from the resevoir and out the bleed screw, you pull the fluid out by opening the screw and applying vacuum. You keep refilling the resevoir with the fresh stuff as the used fluid is bled out of the system.
The Motive bleeder is the more "idiot proof" way and a lot easier.
