I bet they dropped in a 32b/64b phy next to the existing 20b/40b phy. (Code reuse! -> Ship fast! -> Profit!)
And they never tested 32b/64b from the ground up (e.g. the way you might, by starting with a 0/1 pattern on a scope, moving to 8b/10b, then moving to 32b/64b. They jumped straight to 32b/64b testing: pass==done
