Eval-ADV7612-7511 schematic no pull-up on DDC SDA?

We have a design based on the Eval-ADV7612-7511_rev0p1 schematic.  We followed the schematic closely, including the Do Not Populate in R114/R119, which are the pull-ups attached to the ADV7612 DDC SDA lines.  As a result the Rx DDC data lines don't have a pull-up but the SCL lines do. 

 

What was the reason for this?
