I have tried to figure out why Pella does this. I have heard the track
clean thing but the track is on the outside and gets iced up so you can't
get out in winter, so how does it stay cleaner? The wind thing just seems
silly what if the wind is blowing the other way, will it suck the seal
open?


I've never had an ice problem in 10 years or so that I've had it.. If the
wind is blowing the other way, the windows and doors on the other side of
the hose should be closed and blocking it. You evidently have never felt the
wind coming off the ocean in winter.
