i hope he can't, that is far from how it works,
in a mismatched load situation as the op has here the meter reads the sum of the forward power plus re-reflected power,
the sum of the forward power plus re-reflected power can be higher than the transmitter power, you can see that on your meter as extra watts that you don't have from the transmitter,
reflected power is not lost power/power that is not radiated,
reflected power arriving back at the transmitter is re-reflected / summed with the forward power and sent back towards the load where some will be radiated and some reflected back towards the transmitter to be re-reflected,
the loss is coax loss, plus if you don't have a tuner at the transmitter your transmitter may see an impedance looking into the coax that it cannot deliver its full output power into.
