The button lights up when you spin the wheel backwards!

Anyone else noticed that if they spin the rear wheel on their decoy backwards that the button lights up for a short time? I noticed mine this evening because I had it upside down to fit a new tyre, refitted the wheel cranked the pedals to distribute the sealant around and then span the wheel backwards just before I turned it over, that's when I noticed the button was lit up before it faded out again.
This was without the battery in the bike.

Yeah. Shimano motors do that
