I guess so.
While at an underground site, skip the archery phase, the maneuver phase, and The Balrog cannot be assigned to skirmish companions of strength 6 or less I Think "and" is the magic word that resolve our question here since it links the skip phases and the assign thing to the mandatory condition of the game text "While at an underground site...".
If we have a dot after Manuever phase and then start a new sentence wit The Balrog... we would have two diferent habilities but that´s not the case.
Big trouble to rangers and elf archery huh?
