It has to do with the gain of the stages before the main compensation
capacitor.

Slewing happens when a stage clips before the main compensation
capacitor.  So it's possible to build an opamp that never slews
(infinite slew rate!) if the main compensation capacitor is placed at
the input to the first diff amp.
