No, HTML 4 spec says [1]:

  "Because HTML uses the Unicode bidirectionality algorithm, conforming
   documents encoded using ISO 8859-8 must be labeled as "ISO-8859-8-i".
   Explicit directional control is also possible with HTML, but cannot be
   expressed with ISO 8859-8, so "ISO-8859-8-e" should not be used."

So the spec says exactly what you mean. Maybe you were referring
WD-html40-970917 or WD-html40-970708. Of course, that was an error.
