No, I don't know that at all.  I understand the reluctance to use that 
terminology, but strictly speaking you're wrong.  Reactance networks are 
reciprocal ... they don't care in the least which direction power is 
heading.  The combination of the feedline, the "antenna tuner", and the 
output impedance  of the transmitter reflect back along the feedline to 
the antenna the same reactance that you would use at the antenna feed 
point to zero out the total reactance there ... i.e., "tune" it.  The 
only difference lies with their respective losses., and if you had 
lossless feedline and lossless components there would be no difference 
at all.

It's basic network physics, and reciprocity is reciprocity.
