Your ':syntax' commands are not reset when you just retype them.
To reset your syntax commands, you need to add something
like this at the beginning of your sequence of commands:
:syn clear | syn on
or
:syn off | syn on
The 2nd point: I'm not sure if your 'syn region' accounts properly
for '{' inside comments/strings. Is it possible that '{' inside
comments or strings confuses it ? I'm not sure.
