Russia was banned from competing in the Olympics due to major doping concerns, hence them being represented as ROC. Yet, the commentators CONTINUOUSLY refer to ROC as Russia. As such, it undermines and trivialises the ban on Russia and it's contrary to the stipulations for ROC competitors (which is NOT referring to them as representing Russia). Channel 7 commentators may want to start referring to ROC competitors appropriately, rather than ignoring the international ban on the country.
