I think the point is to have VOX inactive until PTT is keyed.  In this mode, 
PTT wouldn’t key the radio, it would simply activate VOX.  If PTT was not 
keyed, the radio would not respond to audio and key the transmitter, even with 
VOX turned on.

Another way to do this of course, would be a switch in the audio path of the 
mic (the reverse of a broadcaster’s “cough” switch).

Interestingly (to some perhaps), my CE-100V works this way with its D-104.  
With PTT not pressed, no DC is applied to the FET preamp in the mic.  So I 
leave the radio in VOX mode, but still have to invoke PTT on the mic for the 
VOX to actually work.  It is actually quite handy — when you’re not going to 
talk for a bit, you can cough, sneeze, yell at the dog, whatever, and the radio 
won’t respond.
