No. It is correct that the impedance seen by the generator is 50 ohms but the
SWR is unchanged, regardless of the line length. The SWR is entirely
determined by the impedances of the line and the load.

The same, for the above reason. The impedance seen by the generator would
change, though (see Smith chart).
