Seems easy enough to work around. Just fill the extra space with completely different products. Put the other seller's products in a different location, also mixed in with other stuff. The rule would be that you can put two products together if they are either the same seller (in which case you don't need to distinguish) or a different product (in which case you can distinguish visually). Amazon already mixes different products in the same slot in order to optimize space anyway.
