Why global response filters would not be executed but bounds one will in
this case ?

I guess given that global response filters are executed after bound
response filters, should they be given a chance to process a response
too, right ?

The idea was to try to simplify things without having special cases for exceptions thrown here or there. Thus, Section 6.7 states that the response filter chain is always executed, regardless of where the exception was thrown, but exceptions are mapped only once.
