"the fact remains that the company did not file any details about the split, so the A/S remains at 4,000,000,000"
While this may be true, one IHub user claims to have been told that a reverse split registered in Nevada will effect the A/S.
I see your reasoning and you may very well be spot on, but until there is word from the company or clear information stating the A/S and O/S, I would not say with 100% certainty that the A/S is 4 Bil.
