Yes. I used the term hidden primary in the past, and technically there would be 
no reason for a setup hidden primary -> primary -> secondaries, as you have two 
single point of failure (SPOF) there. I wouldn't deploy that. For me these 
words (master/primary, slave/secondary) alway have been synonyms.
