Torsional Wind Load Cases

Hello all (Happy Friday),
 
In reference to the torsional wind load cases that are shown in ASCE 7-05, Figure 6-10 (p. 54, note #5), has anyone developed a feel for what building geometries or heights seem to really kick in a strong reaction to these effects, to where they control the design of certain portions?  I'm trying to develop some intuitive knowledge of the effects of some of these load prescriptions.
 
Thanks,
