There is no discrepancy, protein in excess of requirements is oxidised to provide energy.

If for example a bodybuilder or strength/power athlete ate 1.6gPRO/kg/d when they only required 1.2g/kg/d then 0.4g/kg/d of protein would be broken down to provide energy.

I think what you're missing here though is that people such as elite endurance athletes, pregnant or lactating women, children/teenagers, the elderly, people with low energy intakes etc may require up to 2gPRO/kg/d which is far in excess of what any bodybuilder or strength/power athlete in regular training would need.
