I found a confirmation in the Futabasha Castlevania: Byakuya no Concerto Official Guide. The section that details the cutscene that follows after fighting Maxim in Castle A says the following:

闇に染まったかのように見えたマクシームは実は正気を保っていた.

"Maxim who appeared to have been tainted by the darkness actually retained his sanity".
