I don't think so mate . Modern day regulators are built to reject any excess feedback .
But give me some little time and I will back this up with fact if I can .
In paralleling two LM7805 regulators that are producing 5.2 V and the other 4.8 V , as load current increases, the higher voltage one carries all of the load current until it goes into current limiting at around one Amp, at which point the voltage drops from 5.2V to 4.8V, and the load current can increase up to where the second goes into current limiting at about 2A .Now I think this can be applied to the regulators in this circuit ,so they have another self regulation going on sufficient to avoid problems up to the sum of allowed current for both.
