I agree, having complex impedance involved makes this all even more complex :)
Two examples I used are extreme special cases that do not apply to any other (either to antenna with complex impedance or to "random" t-line lengths), but the two questions are still the same:
1) is the "transformation factor of a random t-line length "symmetrical"?
if the t-line "adjust" Z2 to Z1, then the same t-line adjusts Z1 to Z2 (apparently it's not the case, with rare exceptions like lambda/12 t-line with strictly resistive loads)
2) what happens with reflective power in scenario explained above (total mismatch + antenna tuner + lossless line)
