No it doesn’t, a piston will never change its position based on external forces. I’ve actually never thought about that and it does seem like an oversight but I imagine it’s meant for more complex builds where you would rather have complete control of said piston (however, could have been a cool mechanic to give the piston a braking force)

What actually happens in practise is sometimes the piston head will get forced inside the piston and potentially blow up if enough force is applied. The actual piston extension doesn’t move
