Exactly. That is why he uses a very simple tool to measure the BB to make sure it is within spec. The video does suggest that no QC was done on this particular frame before sale.
But honestly, crap happens. Almost everyone can make some good frames. When things are bad, how does the company act? That is what is important to me. Will Open explain this issue and if it is a defect, replace it?
