When SQL Server is using memory dynamically, it queries the system periodically to determine the amount of free memory. Maintaining this free memory prevents the operating system (OS) from paging. If less memory is free, SQL Server releases memory to the OS. If more memory is free, SQL Server may allocate more memory.

Dynamic memory with SQL is good for letting the memory expand as required and taking the pressure off the disk subsystem as SQL can hold more in memory. It's a bit of a swizz though in the real world as you are supposed to set the "Lock Pages In Memory" (LPIM) setting to stop the OS from taking memory back from SQL, which can be bad, so you end up creating a one-way street.
