is a seller allowed to bid on their own products, via another account, to increase the selling price?

i bid on 2 identcal items from the same seller, i was out bid on both items by the same person, this person won both auctions and now both items are re-listed, seems a little suspicious

Does not appear to be shill bidding.

This is what the sellers deals in so they just relist ended items as they have more of the identical item.
