That's the catch: they have to read the full thread and then respond... in 18 seconds on average! That is a lot. I can barely read a decent-sized paragraph in 18 seconds; and the average typing speed of a professional is 50 - 80 wpm; which means even a 10-word response will take around 10 seconds to type. So you have 8 seconds left to grok the entire context and form a coherent response! And do this for hours at an end.

Yes - I concur that if there is a context switch - you'll run into some performance issues, good point. This suggests then that the system performs best when people are doing back-and-forth on a single thread.
