Read the post in context, and read the entire thread - including later posts - and see what effect Ted had on it.

If you read what he was replying to he was completely off-track in bringing up the stuff be brought up at all, and as the thread progresses he got increasingly into Alice and Bob kookiness and intentionally inflammatory hypothetical scenarios.

There's other comments which do a pretty good job of explaining why asking 'innocent' 'statistical' questions like this is a really bad thing to do, which I didn't even totally grok at the start of the thread, but it's pretty clear if you read the whole thing, and it's also pretty clear that Ted entirely refused to be educated.
