wintitlematchmode multiple instances?

I just have a quick question that I cannot seem to find with a search anywhere. I have two scripts that are running simultaniously but i was wondering if my wintitlematchmode will effect both of the scripts running, or if i can have seperate opt parameters for each script.

for example i need my "auto4" script to run in opt('wintitlematchmode', 4) But i need "failsafe" to run in opt('wintitlematchmode', 2) at the same time. Is this the normal way or is this option going to effect both scripts together? thanks in advance
