They probably wrote the tutorials before they set the GF ability learning order and GF getting sequence.

"okay, this is at the start of the game, quezacotl, shiva, and ifrit are tehf irst three, so let's use them.'

then later, in the storyboard room:
"okay, we can only have two characters, so let's give them two GFs."
"We need the player to figure out what's going on."
"Okay, that one chick will be a teacher, make her give the Playable Character a tutorial"
"What if they accidentally select not to see it?"
"Make it occur automatically"

Then, in the fun things scripting room
"Hey, we need some filler for this garden network thing."
"Yeah, and we need to put stuff in the Help menu."
"Well, we have a couple of tutorials they've made, add a reference to those."
