Got it, thanks. In fact, I simplified to this:
Object foo = (Int64)0;
Int64 foo64 = (Int64)foo;
Int32 foo6432 = (Int32)(Int64)foo;
Int32 foo32 = (Int32)foo; // Throws InvalidCastException
And I confirmed the behavior is the same in .Net and Mono. So everything makes sense; it's just something I didn't know before.
