The reason for a movable bellows-type seal is to allow the door to be part of the cabinet while allowing the suspended mechanism to move on springs, dampers and shock absorbing struts to isolate vibration. Large commercial machines where the door seals right to the cylinder are like the first Bendix where the door sealed right to the cylinder; neither have suspension systems and must be bolted down to operate. They actually have two seals on the door, one that seals against the lip of the revolving drum to prevent items from escaping and then a more flexible water tight gasket that seals the door against the outer tub. Non-suspended washers usually cannot spin as fast so in a commercial laundry, the laundry gets put through an extractor before drying or ironing. Your ASKO has the inner door to seal against the suspended mechanism and the outer door that is part of the fixed outer cabinet, sort of like the first Westinghouse Laundromats in the 1940s here.
