Yes it does in some cases of Vdd/Vpp sequencing, if MCLR is disabled, and if
you want to verify at the Vdd limits.  Why does the programmer have to power
the whole target circuit instead of just the PIC?  Since your target circuit
requires substantial current, isn't it's power isolated from the PIC's power
anyway?

If you have the kind of PIC and the conditions are such that Vdd can be left
on all the time and you don't need multiple Vdd readback, then you can leave
off the Vdd connection between the USBProg and the circuit.  You do have to
tell it what the target Vdd level is, which is done with the -VDD command
line option of PIC_PROG.
