Yes, it is something about having the blood removed and stored that makes it contaminated. Not sure that is the proper word, but you get my drift. The "current therapy" thing is for non-blood cell components, like clotting factors, albumin, that sort of thing- to treat a specific disease with your own blood components, but not a transfusion with blood cells. Cell-scavenging, like I described with cell-saver technology, during a surgical procedure is allowed, I believe because it is kept in "circulation" with the blood stream, and not removed and stored.
It is all very confusing, but it is to conform to a specific Bible quote. One nice thing is that you are only disassociated from the faith if you voluntarily have a transfusion. So it is OK if it is done while you are unconscious and the providers did not know (maybe the note in your pocket or wallet got destroyed with your clothes, or stolen, whatever). If that happens, it had nothing to do with your faith.
