The pipe is connected to the bottom of the airbox, which is where the crankcase vents into... The oil that accumulates in the tube is basically from when the crank case is pressurising (typically at high, constant revs with a big single) and forces a little oil out and into the airbox.

Certainly after changing the oil and a few high speed runs mine tends to have about an inch or two of oil in there (which if you drain it actually equates to very little) after a few hundred miles... but it doesn't seen to fill up any more than that though, and the oil level at the dip-stick remains constant... even if you empty the tube and it fills back up another inch or so.
