Driver is flatter: less tilt, more around the body
Translating the same swing to the driver: because the driver is the longer club, you don't set as much forward tilt toward the ground and the club travels more around your body on a shallower, flatter angle than with an iron. The coach stresses it's the same motion - still elbows together, still left shoulder under the chin to the top - just a different, flatter angle because the club is longer.
