It's less the pneumatic itself and more of the connection with the shifting shaft. This is helped a lot by having a second pneumatic on the other side, but thats not ideal. With only one pneumatic theres a huge moment on plate connecting the pneumatic to the shaft. That will want to bend both the plate and the pneumatic shaft and generally push everything out of alignment. It's very important that that connection and whole assembly be very stiff. Once again though, if there are two pneumatics then that moment is balanced and it's less of a problem.
The pneumatic layout on the GRT gearbox this year was designed for just one pneumatic and designed to deal with this moment. There are two on there because we were having a bit of trouble shifting in a few extreme conditions so added the second for safety, there is improvement to be made to get back to one.
