Market makers are obligated to keep lots of orders way outside the NBBO in order to maintain an "orderly market".
If a trade occurs at $10.00 and then the next trade is $12.00, that's considered "not orderly". So a market maker must keep orders at $10.00, $10.20, $10.40, ..., $11.80, $12.00. This way if someone comes in and buys everything then the sequence of trades will be $10.00, $10.20, $10.40, etc.
