This is because latex block can be evaluated, which gives:

  #+RESULTS:
  #+BEGIN_LaTeX
  latex
  #+END_LaTeX

i.e., the generated results appear only when using latex export backend.
The original block is removed thereafter. You can use instead:

  #+BEGIN_SRC latex :exports code
  latex
  #+END_SRC
