Sorry - I can't agree.

The tuner never made the phase angle of my load zero - the current 
through the resistor/capacitor combination, and the voltage across them 
were still out of phase, even when the tuner matched the load to 50 
Ohms. What did become zero was the phase angle of the combined tuner/load.

I think we're playing with words, but I think it's misleading to use 
words which suggest that the tuner has in some way "altered the load" - 
it hasn't.
