All of these examples execute as expected.  It is not always possible to
automatically identify and remove the results of a code block execution.
Remember that Org-mode files are just plain text.

Inline code blocks like the above are mainly intended for use during
execution, not to be executed in the buffer during normal use.

The above is not valid elisp, but the same statement still applies.

By definition "raw" results are not marked in any way and thus can not
be removed from the buffer.  Maybe try ":results wrap" if you want
un-quoted un-exampled results which can still be automatically removed.
