I'm obviously missing something here.
A smaller frame (shorter seat tube) will force you to rais the saddle in order to get proper leg extension. When you raise the saddle higher, it also becomes higher in relationship to the bars.
Thinking in reverse, the bigger the frame, the lower you can run the saddle and still maintain proper leg extension, and you won't be reaching as far "down" for the bars.
For the record, I'm only 6' even and ride a 60cm bike for that exact reason. Comfort when riding for me, standover be damned.
