I'm not sure I understand the situation you are describing.  (The word
"margin" is too overloaded, even if we confine ourselves to Emacs
parlance alone.)  Could you please provide an example of such a
paragraph?  Then I could reason about it.

They are not "different", they just follow the base direction of the
preceding paragraph.
