I thought the same as well, but then I wondered if the force of sealing the door and fastening it down will be enough to quickly split that seam.
So, the plan is to put the pinch welt on as per the picture, but then I am going to add an extra rubber gasket behind that so even if water gets past the first seal, hopefully the second seal will stop it and drain it down to the bottom, between the two seals.
