Yin yoga - doing longer pauses/breaks after every pose - yay or nay?

I started attending yin yoga in my yoga studio and we would take 2-3min of pause in a resting pose (shavasana, child's pose, lying, shavasana with bolster under back/upper back, etc) between each 5min yin pose, to feel the diferrence in the body and whatnot.

I was checking yin yoga book from Kassandra Reinhardt. She has a 60min yin yoga practice - 12 yin poses, 5min each, and there's no talk about the in between pauses.

Why do some people practice yin with pauses and some don't? How do you do yin yoga?
