Not true. A local frame is one that only valid at a point or in a small region centred on some point (with small defined with reference to the curvature tensor components).
Nothing to do with observers or events.
And the converse is that non-local reference frames are valid for an unrestricted region of spacetime i.e. a global frame.
Chuck asked you a question, would you care to answer it?
I think the answer is quite important because you seem to be making a "heads I win, tails you lose" kind of argument: It seems that if it turns out that a string theory is a good description of nature you'll jump up and down shouting that the quran predicted it; whereas if it is discredited, you'll claim that you just misinterpreted or start denying that you ever made the claim.
