If you really have no idea why this is important, especially for tanks and healers, than I question how good a tank/healer you are/could be.

As an example, many, many new tanks will spin mobs and bosses, not group mobs properly, etc. They have aggro, so they're good, right? Its usually when they level a melee job that they learn that they are, in fact, not good tanks, and making their dps crazy. Tanks that level healers can see just how hard it is to heal a bad tank, and work to avoid being that.
Healers that level tanks will learn how its better to bring mobs they steal to the tank, rather than start kiting like crazy (same for ranged dps)


Overall, though, the tank/heal/dps requirement is for the role basics, and basic interactions between roles, not job basics (the thing you are so hung up over). This is for people who are new at the game, maybe getting to the early levels of their job; classes don't play all that differently than each other at low levels, so a PLD can teach a new MRD how to tank and so on. If anything, it should require a lv60 tank/heal/melee(DRG/MNK/NIN)/ranged(SMN/BLM/MCH/BRD) instead of just DPS, because melee have different issues than ranged.
