I am not sure if this is needed? Should be same as XBAR pins column

With normal caveats, that if two or more pins show the same XBAR value, you can only use one of those pins for XBAR.

Is it not useful in the same way it's useful to know which pins are capable of GPIO, PWM, ADC...?
Are you saying all the pins that are on a xbar can be used for quad encoder inputs?
If so then yes it's redundant having the extra column. But then it's still not clear from the current diagram that those pins can be used for quad encoder inputs. So maybe a note or legend somewhere on the diagram indicating this (that all pins on xbars can be used for quad encoder inputs, and anything else they can be connected to) would be a better solution.
