It's a safety feature designed to reduce compressor freeze/wear issues. The A/C compressor as you know is on a parasitic pulley that can shut off. But it's not designed to operate at high speeds for long durations, and all cars are optimized for the mass market, which typically doesn't cruise over 90.
My car does the same thing, if you want to adjust it I wouldn't be surprised if you can in techstream via OBD II. Freeze shouldn't be an issue when it's 110°, but wear on the compressor will still be higher at high RPM.
