That is a requirement for all aerobatic aircraft. Try jettisoning the door to the inside of a spin. Sometimes, things just don't work out the way they were planned!
I must admit that I cannot envision any aerodynamic force that would keep the door from opening with a push in a spin to the right but I am not an aerodynamicist. Also I would imagine that the FAA would require that the door would be able to be easily jettisoned in both right hand and left hand spins before certifying it for aerobatics.

We also had a Christen Eagle crash here a couple of years ago that could not recover from an inverted flat spin. Both the instructor and student were killed. The crash investigation revealed that, even though the jettison handle was pulled, the canopy did not release until impact. Also, both occupants had there harnesses off before impact.
Do you have the N number of that plane? I would be interested to read the NTSB report.
