Could be a someone behind the MM with an account at their firm, but on OTC and BB stocks, sometimes these MM's trade for their own accounts as part of their strategy. For example, you can take risk and buy for yourself as a firm by making a market in a particular stock, and if you are correct, and you own 10,000 shares of stock at lets say $1, then it goes you to $3, you put it on the ask and make the spread as it sells for a $2/share profit. Same on the short side. That said, it is supposed to be regulated, and their should be a trail through monthly disclosures to NASD. But those are internal and visible only to the firm and the NASD. they are trading strategies so not publicly disclosed unless there are violations.
