He probably means "stabilized using gyro and accelerometer" (ie, release sticks = evens itself out) as opposed to "just stabilized by gyros" (ie, release sticks, copter stops any rotation but keeps pitched/rolled position).
Sure, learning to hover in one general spot is doable in 10 minutes. I wouldn't call that "learning to fly".
What about very basic maneuvers like landings (no bouncing around, no dropping from too high, and at the spot where you wanted to land) or circles/eights, dealing with ambiguous orientations when your copter is high enough (~ 6m ?), nose-in flying / dealing with control reversal and recovering from orientation loss?
