Hard to believe the sled is not tracking to the blade considering the
sled is tracking to the miter slot (via miter bar), and he said the
blade is parallel to the miter slot

Yes that would be hard to believe but if the back of the blade is hitting
the wood the sled would not be tracking correctly and most likely because
the slots are not aligned properly to the blade. Or he is letting the wood
slip.
