Since I manage to partially answer the question, I have to make some corrections in the question.

I fill in some missing details so the newcomers can at least understand the statment of the main theorem.

Apr 30, 2017 at 9:56 comment added Hua Ying @AnthonyQuas OK, you are right. Here is what is confusing me. I am not sure why the identity $AA^*+B^*B=A^*A \otimes Id_{V_1}$ implies $Av-g=B^*BM^{-1}g$, where $v \in V_0$ is an approximate solution of $Av=g$, for $g \in V_1$, given by $v=A^*M^{-1}g$. Can someone help me with that? Thanks.
Apr 28, 2017 at 22:52 comment added Anthony Quas Welcome to MO Boris. I don't think this is a very good question for this web site. You're basically asking someone to digest a paper for you. This might be fair game for a very well known paper, but not for this one. Rather, a reasonable question would be something more specific.
