If that were true no water would ever come out. It is all about which side has more pressure. When the ski is upside down water comes into the breather holes on the hood and/or pole. That pressurizes the air which pushes the ball away and the air escapes. Also, but not that it really matters, the versaplug is usually not immersed in water when the ski is upside down, at least not until the ski sinks.
On a side note, some people bitch about the versaplug draining too slow because it has a smaller diameter. That would also mean that it lets air out slower and the ski will take longer to sink if it turns upside down. If you are really worried about your ski sinking when it's upside down, make damn sure it floats with the engine bay full of water or don't use a scupper.
I prefer the versaplug max over other scuppers. It does not leak and there is no rubber to deteriorate to start leaking later.
