Yes, the one equation was displayed as a preview. 

Maybe I was not clear in my directions so try this bit:

--8<---------------cut here---------------start------------->8---

1. Copy the text between the `cut here' lines to its own org buffer.
2. Place cursor in the eqn1 src block.
3. Type ~C-c C-c~ and respond to any prompt about evaluating with ~y~.
4. An eqn1 results block should appear with a :results: drawer
   containing an equation in it.
5. Type ~C-c C-x C-l~.
6. The equation should be previewed in the :results: drawer.
7. Export to LaTeX Buffer with ~C-c C-e C-b l L y~ 
8. Only an enumerate environment and the equation should appear in the
   LaTeX buffer.

#+name: eqn1
#+begin_src latex :exports none :results drawer 
  \(y = x\beta + \epsilon\)
#+end_src

#+call: eqn1() :results latex

--8<---------------cut here---------------end--------------->8---

IIUC, the question is 

:  when I export (as in item 5 in the list above), will the LaTeX buffer
:  open in a window to the right of the one containing the org buffer?

This is what happens in my setup when I have the org buffer displayed in a 
frame with just one window.

But how windows are displayed depends on many factors. See (info "(emacs) 
Windows") for some of the details. So you may need to customize or resize your 
frame to get the same behavior.

Um, I don't see how this gets to the original question.

There are probably a lot of opinions in the org community about how well org 
handles previewing output. For me it works well. YMMV.

HTH,
