I’m not sure what you think he got wrong, and it’s certainly possible, but there are no 467 MHz range channels in FRS which allow 2 watts. 8-24 are in the 467 MHz range, but they’re limited to only 0.5 watts ERP. The 462 MHz channels 1-7 and 15-22 are two watts.
The eight 467 MHz Main Channels in GMRS (generally reserved for repeater inputs, Fixed Stations, and short term testing) are not allowed in FRS.
