It's not. Hospital personnel do indeed ask you the same questions repeatedly to make sure they're treating the right person, but online vendors rarely have such high consequences attached to getting this wrong.

I suspect the real answer is that when they finally hand you off to a live human being, that human is sitting in the boiler room of a third-tier contractor on a different continent than the main headquarters of the business, and they have no idea what you're currently looking at on your screen. It's technically possible to do this handoff with a complete picture of how the user got there, but that requires a degree of technical integration most companies don't seem to want to pay for.
