33 | New 33-Yard PAT in NFL Football Games?

As someone who often decodes '33', I'm wondering where the '33' is with the new proposed PAT rule for the NFL.  Do the math with me.

• The End Zone is 10-yards
• The New PAT is at the 15-yard line
• On a PAT snap, the ball is typically hiked back six yards
• 10+15+6 = 31
• If the ball were snapped back 8-yards, it would be a 33-yard attempt

So after doing the math, I want to know why there is all this talk of a 33-yard attempt, when on average, it should be a 31-yard.  Is it just another opportunity to broadcast the number 33?  Are kickers now stepping back an extra two yards?  What is up?
