There could have been a combo washer-dryer at the end, or it could have just been a base cabinet. Many people would not have wanted laundry equipment in the kitchen. I've seen various configurations of these GE Kitchen Centers, with either wall ovens like the brochure shows, or under the cooktop - or no oven at all. I doubt these were stock items, but rather manufactured to order. Would be interesting the see the GE dealer catalog for these.
