MUSHRA: Hidden but known?

Part of the MUSHRA test (ITU1536) is a hidden reference signal and hidden anchor signals.
I always thought that "hidden" meant, that the listener does not know about the hidden signals at all.
But I do not know if this is true. Does "hidden" imply  that the listener does not know about the hidden
signals at all?  Or does it mean the listener might  know that there are hidden reference and anchors but
he/she does not know where they are? And if he/she  might know, should he know,
i.e. should it be told a priori?
