This is when I noticed a problem,
even though the splitter was lined up with the blade, the wood would
bind between the splitter and the fence. The finishing blade is the
same width as the splitter.

I'd double check the alignment before doing anything else. If the kerf
is not binding on the splitter itself, then the blade and splitter
thicknesses should be compatible.

If wood is binding between the splitter and fence, it suggests that
distance from the fence to the blade is bigger than the distance from
the fence to the splitter. This would be an alignment issue.

The other cause that has been mentioned is the particular board you're
cutting has internal stresses that are being relieved during the cut
and deforming the board. Try other lumber and see if the problem goes
away. If you do have some wood that is moving this much, bandsawing it
would be safer.

Good luck,
