I'm not sure I understand.  Are you saying that these two
logical-order strings are ``equal''?

   he said "I NEED WATER!"
   he said "I NEED WATER!<RLM>"

Perhaps you meant removing the directional marks after resolving the
explicit embeddings?  But if so, the embedding resolution leaves
behind information that is not part of the string itself, so
comparing the strings alone after removing the marks won't tell the
whole story.

What am I missing?
