Air Flow Direction
If the coil is downstream from the furnace (left to right in the video), then it doesn't matter which way the apex is pointing. It's designed to go either way for ease of installation in either air flow direction.
If the coil is upstream of the furnace, that is definitely wrong and should be corrected or else the heat exchanger will rust out prematurely.
You can choose to do what you want, but you cannot choose the consequences.
