Default Bad bpv diaphragm?

I recently(today) aquired a used Turbo XS bypass valve from a user here on AW, and after recieving the valve I noticed that if I press the piston upward and plug the nipple, the piston still closes. Does this mean the diaphragm is bad on the bpv? Thanks

I think my TurboXS did the same thing and it holds boost fine.
