Is there no need for a 2nd rise post shaping?

I see from the recipe on which this Scallion Pancake Challah was based that it too does not have a second rise. My experience with braided challah has been that in the time it takes to roll the strands and then braid, a fair bit of rising occurs, so the absence of the second rise does not seem troubling. Also, the challah recipe on which this one is based was tested and approved by the test kitchen, so I would go with the Scallion Pancake Challah recipe as drafted. ;o)
