It's called "bud powering" and it's basically a bug with the way pistons are being powered but it can be very useful in some contraptions. People have used this concept to detect block updates in the older versions of the game when we didn't have observers. There are tons of videos on youtube explaining how bud powering works.
Someone could explain to me how the piston is activated here?
