Even if the spec is labeled "Floor Dimensions" or "Floor Area", the numbers still seem to come from the over all size of the tent, not the available interior room.
Now I can't say anything specific to the MSR #2 as it's an unusual tent design and I've never seen one in person.
But based on my experience, it is quite possible that the dimensions listed in the specifications are based on where those triangles in the corner (for staking out the floor of the tent) stretch out to and NOT the usable interior dimensions of the tent. The actually usable interior length might be only 78" to 79"... and that's at the ground. But you're likely laying on a pad, your head is three dimensional, and the walls all seem to be sloped.
So if my experience holds true for the MSR #2, you either will not fit (without turning on the diagonal) or at the very least, your head/feet are going to rub on the tent walls.
