I won't quote the whole page but he goes through the calculations for determining the deceleration on a specific bike and rider. At the end of the discussion he say:
Another conclusion from this calculation is that a deceleration of 0.5 g (4.91m/s^2) is almost the maximum that can be risked by a crouched rider on level ground before he risks going over the handlebars. We can calculate the maximum possible deceleration as a proportion of g by setting Fv,r = 0 in the above case. Then taking moments of torque around point 3 [in Figure 7.5), we have...
Bicycling Science, 3rd edition, David Gordon Wilson, 2004, p245. Here's a (very) crude reproduction of his figure
As you can see "point 3" is over the front wheel. "Moments of torque around..." implies rotation about that point, not simply lifting the rear wheel. Simply lifting the rear wheel isn't "going over the handlebars". His language is very clear.
