There's a mistake. It's incorrect even for $a=0,b=0,U=I$. In this case the correct formula is
$$
|\phi\rangle \otimes |B_{00}\rangle = \frac{1}{2} \bigg(|B_{00}\rangle \otimes |\phi\rangle + |B_{01}\rangle \otimes Z|\phi\rangle + |B_{10}\rangle \otimes X|\phi\rangle + |B_{11}\rangle \otimes XZ|\phi\rangle\bigg)
$$
but their formula swaps $X$ and $Z$ in the ...
