I don't believe she was ever not going to perform, as that would just be unprofessional and quite un-Ayu-like.

- Fans do not react well to the addition of Urata to most of her set
- Setlist is changed slightly with Last angel at second concert
- Ayu is pressured to change setlist even more, but does not as Urata [and maybe JUNO as well] is being marginalized by avex
- Ayu decides to not perform last in Tokyo (perhaps due to the friction between avex and herself this time around... thinking it not really being appropriate to represent the finale of an avex summer event?)

The way it sounds to me is that she reached a decision on her own to not perform last due to lingering doubts in her head, hence "declining" to perform last not declining to perform. She'll probably be back to last next year, but it's still really depressing how this has affected her and probably stressed her out beyond belief in the last few months.
