I have a possible explanation for the omission of that line from SNAI and SNAII.
Before SNAIII, all the creatures on the SNA list are neutral. There are no Good, Evil, Chaotic, or Lawful creatures.
In SNAII, there's Elemental (Small), which can be an Air, Earth, Fire, or Water creature, and so the line is applicable. But I can see someone glancing down the list, noting that the spell can't be used to Summon any non-neutral creatures, and assuming the line is unnecessary.
However, even with the omission of the line, SNAII is still a summoning spell, so the lines in all the other SM/SNA spells that state "
When you use a summoning spell to summon an air, chaotic, earth, evil, fire, good, lawful, or water creature, it is a spell of that type" are still applicable, and SNAII used to summon a Small Fire Elemental would be a [Fire] spell. (Hence why I said "room for argument" - I could see someone saying "SNAII doesn't have the line, so it doesn't become a Fire spell!", but I'd disagree with them when they did it.)
