That is quite astute, and yes, I will confirm that the example above was born of flawed UX and consequential misunderstanding. Also that the cherished relative in question is a perfectly reasonable, intelligent, and thoughtful human being, I might even say a notable systems thinker in their own field, but otherwise a layperson with regards to email; so the blame attaches entirely to the interface even though the remedy sits with the individual.
As a counterpoint however, I also have a story about a SVP at a high-profile boutique development shop (one of the "fast five", for those who were around two decades ago and remember the term) who habitually filed important documents in the handy wire basket on their desktop. One day, they were enraged to discover that months of work had suddenly vanished. Imagine being the staffer who accepted that particular call for deskside support.
