Maybe -- and I'm guessing here -- he's talking about slurring from, say, Bb up to a C on a BBb tuba, and the slide is being pulled to bring the C down to the correct pitch.
Without a vent, the vacuum-induced pop would interrupt the slur. A properly done vent would eliminate that pop, which would enable a smoother slur.
That's my guess, anyway.
