The case diameter is the same between 32 S&W long and short. The 32 Short Colt is slightly smaller in diameter. Split brass is most often due to brittle brass (not annealed correctly during production) or other flaws in the case. Even the undersized Short Colt round will usually just swell to fit the chamber.
I've had brand new 32 S&W longs split on first firing due to production flaws. I would expect the shorts splitting in your gun was the same deal. Fortunately these are relatively low pressure rounds and not likely to harm anything if they do split so long as the case head stays intact.
