Help me understand what the 'back side of the bit' means. Was this a

He means feeding the workpiece in the same direction as the rotation of
the bit, rather than into the cutting edge. In other words, on a
standard router table setup, he was feeding left to right instead of
right to left.

Sort of. I was feeding right to left and this was fine for the first
pass on the dado cut. The problem came when I moved the fence closer
to the bit and was cutting the dado wider. The portion being cut was
between the fence and the bit. Rather than reset the fence I decided
to make the second cut by feeding right to left.

Sounds like the same principle of a climb cut only with a reverse feed
direction (right to left), since you had the material between the fence
and the bit.

Normally on a climb cut you are going left to right with the bit
between the material and the fence (and saying hail Marys the whole
time).
