The point if that we don't much about Macedon. Most sources about come from Roman, Persian and Carthaginian historians. The Greek historical writings that survived the Celtic pillages were mostly preserved in Athens, which was not sympathetic to the Macedons, and transmitted to us through Roman manuscripts or sometimes just Aramaic later translations.
There are hints suggesting Macedonian style of combat was actually better than usually thought of - well, before the military reforms of Darius V. It is known that he really borrowed many new tactics and weapons from the Greek... I wonder whether those Greeks might indeed have been Macedons in fact.
But yes, that map fairly overestimates what a tiny nation with few brilliant moments in its history could have realistically have done at any given time without an almost ASBish amount of luck.
