The reason that an RF transmission line should be matched at the transmitter end is to:
transfer the maximum amount of power to the antenna
While matching at the antenna end minimizes SWR on the line, matching at the transmitter end (often using a tuner) ensures the transmitter itself sees the correct load impedance (usually 50 ohms) required for it to operate efficiently and safely, allowing maximum power transfer *into* the feedline/tuner system.
