No it is not. It is merely an inaccuracy pointed out by an expert. For it to be an example of the "Gell-Mann Amnesia" effect sseagull would have to show some sign that they forgot that the wpri can make mistakes when they are reading something not within their expertise. That would be the "amnesia" part.
Plus, is it even an inaccuracy? In common parlance beaker and flask are synonyms.[1] Simply regular people talking to regular people describing some glassware are not as accurate as a chemist talking to a chemist.
