If you read the KJV of the Hebrew Scriptures you will notice that sometimes God is referred to as LORD God or Lord GOD. The LORD God is the second person of the Trinity while the Lord GOD is the first.
Try making the argument from the underlying language, not from English.

Here is an analogy. Suppose we have two people. One is a truck driver, and the other is an electrical engineer. They both own television sets. The truck driver has the owners manual and the remote control, and can operate the television without trouble. But he doesn't know how the television works. The engineer understands everything that goes on inside the box.
Following this analogy, the person who "calls upon the name of YHWH" is the man who owns the television. He trusts in YHWH for salvation, but he doesn't understand how it works. The truck driver can tell you that the television works (the one who calls upon YHWH can tell you that God saves us). The engineer can tell you how the television works (which would be analogous to the quotes you cited to me).
Don't worry, nobody every wants to follow my analogies either. ;-)
There's definitely an engineering joke in here somewhere. Like maybe the engineer can't exactly tell you how the TV works, but he can either: (1)tell you how he would have designed it better, (2)simply bluster with some made up stuff that sounds like he knows what makes it work, or (3)explain to you why it can't be fixed with the given time frame or budget.
