FYI, this is an issue of -- apparently -- English not being Christophe's first language. Darryl's construct, "This is unlike StateChart, where the idea of object instantiation as state is genuinely useful sometimes,..." means "MSM's approach is unlike that of StateChart, because StateChart instantiates state objects, which is sometimes genuinely useful."
I think there was more to the original sentence, which I haven't taken the trouble to recover from earlier posts, which better developed what Darryl liked about MSM's own approach. There was, however, no implication that MSM fails to meet expectations because it wasn't like StateChart in this behavior.
For those for whom English is a second language, I apologize. Few native English speakers learn the language well. We thus make our inherently complex language harder still to understand by our mistakes of grammar, syntax, structure, and even word usage. Add to that the many idiomatic constructs and expressions, not to mention colloquialisms, we use that it's amazing that you manage to converse with us so well.
