Cod you are right about the starter disengaging at higher eng speeds.
However the danger is that it won't disengage as normal now that it has pneumatic power still driving it. At the very least it will be spinning faster than normal before it disengages.
The duty cycle for most starters is 5 min.
So if the starter does disengage properly while while still being driven pneumatically (and then under no load) you only have minutes before the starter self destructs
