If it were, why is the braking force consistent? If it were regenerative, the braking force should be higher if your battery is flat.

Also, what stops the brakes from causing a spike that takes your lipo above 4.2V/cell?

And if it were, why do we see no hint of this on our onboard power meters?
Well, GriffinRU did say that it only spikes your batts when the potential is higher than battery voltage, and enough over the voltage drop on the FET diode. I am guessing it is just shorting the motor, and turns it into heat, but the FET's can control the switching of the 'SHORTING', hence proportional braking.

Also, I have actually tried running the Eagletree in reverse manner, but it does not read anything. I tried using it when charging, it needs to be flipped around I guess.
