The docstring for buffer-offer-save says:

  Non-nil in a buffer means always offer to save buffer on exit.
  Do so even if the buffer is not visiting a file.

But File / Close is not exiting, is killing a buffer. That's not
different of just creating a new buffer, typing something on it and
then doing C-x k <ENTER>.

buffer-offer-save is not intended to protect a buffer against killing.
You can use `kill-buffer-query-functions' for that (or some available
packages, like Noah S. Friedman's protbuf.el).
