Is NEC4 better in this regard?

Neither NEC-2 nor NEC-4 has any problem in this regard. Art's statement

That really is good news. Capacitive coupling between close spaced
wires,
progressive change in capacitive coupling to ground from a
verticle ,or wires
at different spacings and closeness must be a devil to calculate tho I
suppose you can also
insert fudge factors for alignment from impirical results which I
presume is the reason
for program modifications despite the inflexibility to change of
Maxwells laws.
Well you highlight one of the answers the gentleman was asking for so
a forthcoming
complete answer from you should give him closure on this subject
