That's what I'm suspecting.
When I created the PAL damage break patch, I noticed that the specific data I was modifying was the same in both NTSC and PAL, the only real difference was the offset location of the data. Which resulted in Arm's patch not working with PAL versions. Sooo if that's the same general thing that's going on here, perhaps it can be fixed easily? I'd have to compare the exe's to verify this as the case.
