I think you over-read the metaphor. The point is that when people are extremely content in their current job, they're likely to 'bounce' people who are asking them to coffee since it's usually seen as a waste of time. It seems legit to me to consider that there is a tipping point in a person's current job where those inbound requests start being responded to, since the person's mind is open to the idea of some kind of transition, however unlikely.
