For which purpose...?
If all local boundaries are fixed and life and death is settled locally
in each region and ko does not play a role, then the local behaviour of
each region considered together for all regions should equal the global
behaviour. Otherwise the same cannot be said. So why would you want to
consider things "only globally"?

You might create problems for yourself... Globally terminal (for human
players) under perfect play does not(!) imply locally terminal in general.
If your aim is to approach rather than to guarantee perfect play, you
might ignore the global / local difference nevertheless. Maybe such a
strategic cheating by simplification saves computational time. You
should just be aware that your program might sometimes make strategic
mistakes as a consequence.
