I’ve been a meteorologist for over 29 years...and his guess is pretty close to what will happen. The bad side of this storm is on the east and very close to the eye...more so than most cat 4’s. Sorry to bust your snarky bubble.
Notheast quadrant will be pushing surge into the coast if the eye tracks up the coast. That is the main danger in NE Florida and Georgia, rainfall is the primary danger in the Carolinas. And if Matthew pulls a Charlie and tracks just 15 miles further west than expected, it will be even worse. They simply cannot forecast this track with exact precision, which is why folks need to prepare for worst case.
...and I've been an astronaut for 40 and I can say emphatically the moon is made of cheese. AKA I think you are full of crap.
