I follow your reasoning: it assumes a proportional relationship between signal strength and the magnitude of the AGC. Since in this set, AGC is applied to the mixer only, it makes we wonder if the amount of back-bias that the mixer gets from the AGC when a strong signal is received is adequate to reduce the gain of the mixer-I.F. amp. chain, resulting in the I.F. amp. being over-driven.
