Your builder likely has run into a situation where in his efforts to kill a hum, made a swap like this and it worked. It was likely a situational solution that involved many possibilities like a cold solder joint, wire routing, tube location, etc. that combined to kill the hum. Once it worked, he declared a theory that the cause of the hum was the particular side of the bottle and he as stuck with it. I do not have similar experience using one side or the other.

More importantly, why does he want to light the unused side of the tube when he has a split heater? Just light the one side you are using. If one channel uses the left side triode and the other uses the right side triode, when a tube burns out you can swap the tubes between channels and get two free new tubes out of the deal. If you just burn up the unused side, you get no benefit at all.
