Is there multiple ways to cin vector elements?

I have a program that adds multiple vectors in 1 vector. I saw a method of instead of .push_back to add elements and I used it, but I am wondering why this work

Updating an intrinsic rotation with an extrinsic rotation

I am trying to model a Rubik's Cube for a personal project, using Zdog for lightweight 3d graphics. Zdog uses a {x,y,z} vector to represent rotation - I believe
