As I recall, the order they were listed in was important also, in that (when they put in a row, rather than a column) you'd use the left-most category if something fell under multiple listings.
For instance, if someone used a death spell (yes, that was actually a specific spell in AD&D) from a staff, did the target save against Poison, Paralysis and Death Magic, against Rod, Staff or Wand, or against Spell? In that case, PPD is furthest to the left, so that was the one you went with.
That would have been way too logical for Gary. It' just that there were references in the table, and that some columns were applicable for certain types of save unless it was already taken care of in another column.
Paralyzation, Poison or Death Magic
Petrification or Polymorph*
Rod, Staff or Wand
Breath Weapon**
Spell***
And
* Excluding polymorph wand attacks.
** Excluding those which cause petrification or polymorph.
*** Excluding those for which another saving throw type is specified, such as death, petrification, polymorph, etc.
So everything was specific...
