notation for probability distribution (double absolute)

Question

I am trying to understand this term in an equation, but I am somehow confused. Can someone clear it for me ?

$KL(q_2(z_2|x_2)||p_{\eta}(z))$

$ \mathcal{L}{CC_2}(E_2, G_2, E_1, G_1) =\lambda_3 KL(q_2(z_2|x_2)||p{\eta}(z)) + \lambda_3 KL (q_1(z_1|x_{2}^{2\rightarrow 1}||p_{\eta}(z)) - \lambda_4\mathbb{E}{z_1\sim q_1(z_1|x{2}^{2\rightarrow 1})}[\log p_{G_2}(x_2|z_1)]$ It is from a paper: https://arxiv.org/pdf/1703.00848.pdf — Mostafa Hussein, Aug 22 '18 at 09:29
I understand each variable, but I am confused in getting all variables related to each other inside the term itself — Mostafa Hussein, Aug 22 '18 at 09:30

Kullback-Leibler divergence between the distribution $q_2$ of $z_2$ given $x_2$, and the distribution $p_\eta$ of $z$
