Yes, you would pull up onto the middle level and drop your bags with the porters. The you would continue a short bit and go up a circular ramp to the roof to park. You would just walk down with your carryons.
There is also a ramp up to the roof as soon as you enter the terminal area but don't take that one . Stay on the middle level until you drop your bags and use the ramp at the other end of the terminal.

Above you can see the three levels. You would pull up to the middle level (entrance would be all the way down to the right out of view). At the entrance on street level there is a ramp up to the middle level. Porters will be there.

In this pic you can see 2 ramps. The curved one is the ramp to roof for parking and where the person is crossing the street that is the exit ramp of the terminal.
The bottom level is reserved for limos, buses, etc. and the middle level is for cabs and car drop offs and pick ups. Roof is for parking.
