If you buy puts, MM sold puts and will sell shares against since he is holding a deltaLong position from selling his puts (he makes money if the underlying goes up and lose money if the underlying goes down (which is why you bought the put). To hedge that risk he would sell shares against the sold put so that the risk of the underlying move would be covered.

you're right, but yes the concept I'm referring to was staying delta neutral. When people close their put options before expiration, the MM's create buying pressure.
