The idea of a yellow primary in DIR isn't wrong, just unnecessary. The primary is known to be such by the fact that its in your mouth and resides at the end of a 5'-7' hose-no confusion there. The secondary is worn on a short hose-22"-24" parked around the neck on a bungie. No confusion there, either. Acknowledgement that the primary is donated is SOP in DIR. By donating the reg from the mouth, there is no confusion by the OOA diver or the donor as to where to find the reg. It's easy visually as well as by touch alone. Yellow octo's came about because of the need to pick out the octo from all the rest of the clutter on a diver's chest, or hip, or pocket or where ever it happens to be that day when the diver is rigged to donate the secondary reg.
I suppose confusion could come about if someone diving DIR dives with someone unfamiliar with the system and hasn't properly explained how air is to be shared, but equipment is never a substitute for planning and comminication.
