It basically is a cushion for when the door shuts and does block out some water from the door frame.
My seal is pretty tight, when I took it out is was quite hard to get back in. Is it possible that some cars have a loose fit?
I remember seeing on this site somewhere that these seals were falling out of the channel on some vehicles. Others have said that it was tight and they still have water behind the seal.
If we say the water comes in from outside the seal, I can only see it getting in those gaps or at the top ends but not around a tight seal in the channel.
Water can get in those gaps, at the front it has the water going towards the rear of the car due to the cars forward motion. At the rear of the door, any water running down against the edges of the seal could roll into the gap.
