the market maker still collected $22,000 in premium if they bought shares after selling the options, thats motivation enough to fill the entire order at a good price before another market maker does. you can write unlimited options, so without scarcity the bid and asks don't have to change if the buyer can be a little patient.
but if they only tried to keep up with the delta then they might not have bought enough shares and have some losses right now, on that one position
