I see.

There is an important difference between evaluating a buffer and
evaluating a buffer during export. In the latter, Babel has to deal with
replacement values, i.e., code block is replaced by its results. See the
difference between `org-export-execute-babel-code' and
`org-babel-execute-buffer' in a buffer containing only

  src_emacs-lisp[:results raw]{(+ 1 2)}

In this case, your code removes the code (and much more) as
a side-effect. This confuses `org-babel-exp-non-block-elements', which
also tries to remove it. As this fails, it removes a random part of the
buffer instead (probably as a mean revenge).

`org-babel-exp-non-block-elements' and `org-babel-exp-process-buffer'
could probably check if code still exists before trying to remove (and
replace) it.
