You can never have too much existentialism, French, German or Maynard G.Krebs; the idea that a writer is in his existential moment, stripped of his excuses and wholly dependent on his next action to give his life meaning , purpose. authenticity, is exactly the dilemma we discuss here all the time. It is the issue that all these poems-about-poetry attempt to take on but never grasp because of the intangible nature of the issue and because so many of the poets who attempt the task fumble with their poetics. Auster gets to an emotional core--the loss of self one can experience in writing, the dread that the words might be unheard, ;unread, when the writing is done and one is passed on--by the choice spareness of his metaphors.

I wouldn't disagree with you about the poem attempting to bridge different parts of the body, but I think the particulars aren't that important in so far as the real issue is the author's attempt to make contact to an Other , some essential part of one's sense of themself in this life that is dually absent and yet persistent in one's instinct. The question arises, is the writer talking to himself in an effort to join his separate selves, or is he seeking a common bond with a community he has no evidence actually exists? This is the ambiguity and the beautiful ache in the poem.
