This is because src blocks are executed before buffer is parsed. You can
try to call `org-export-blocks-preprocess' on the following buffer
(associated to a file):

--8<---------------cut here---------------start------------->8---
  #+name: bblock
  #+BEGIN_SRC R :exports code :et-cetera
  rnorm(2)+1
  #+END_SRC
--8<---------------cut here---------------end--------------->8---

and see what is really parsed: the removal happens on the Babel side.

Depending on your needs, you may want to use ATTR_LATEX keyword instead.
