The two pins at each end of a straight tube are connected together by the filament, so of course there will be some resistance between those two pins. Otherwise the tube would not light.
The only thing connecting one of the pins at one end of the straight tube to a pin at the other end of the straight tube is the tube's glass (non-conductive) and the enclosed gas, which is non-conductive if not energized.
Your circular tube is simply a straight tube rolled into a circle, two ends, four pins, two filaments still exist.
Did your You-Tuber bother to try to see if the two ends of the tube were connected?
