Indeed, that is our current understanding prior to Joe's thread. On a 3 speed system "low" runs at 100 degrees and "medium" at 106. That means that if speed 1 (on a 2 speed system) covers both these, it must trigger at 100. This didn't happen according to Joe's account. His coolant temperature rose to 105 before the fan started running.
So your logic, fine as it is, unfortunately doesn't explain what Joe reported.
