The distinct difference is that if the increase is absorbed by the sellers, they either leave their prices the same or raise them, but the buyer is always paying the amount listed. If the increase is absorbed by the buyer, they can see the cost and buy it, and then be changed the extra amount at the end. While you are correct that one way or another the buyer will be paying more it is how you present it (buyer raises price to counteract the increase vs seller being charged more directly by the service).
