Boiled down in simplest terms:
1. Tires with XL ratings are reinforced to withstand higher load pressures (For P-metric tires 41 p.s.i) - My assumption is that an extremely heavy (awd- front tires supporting a 4.2L engine) car at high speeds would tend to heat up with a corresponding pressure increase.

2. The 95 in 95Y refers to the load rating that the tire is designed to handle (95=1521 lbs - by extension 4x1521 lbs = 6,084 lbs of gross vehicle weight, which does in fact seem excessive for a car that weighs 3,925 lbs). As probably everyone but myself knew already, Y refers to tires designed to exceed 186 mph. Every recommended tire on Tire Racks site for a 2004 S4 was a 95 load rated tire. I would assume that this builds a margin of safety for how front loaded our cars appear to be.
