The hair tie on the wrist might be a part of the trainer's unique style in the fanfiction world. It sets them apart from other trainers. It could also be a hint at their backstory. Maybe they used to have long hair and had to cut it short for some reason, but they still keep the hair tie as a reminder of their old self. Additionally, it could be used in a plot device. For instance, the hair tie gets lost during a crucial moment and the trainer has to go back to find it, leading to an unexpected encounter or discovery.
In fanfiction, the hair tie on the wrist could symbolize the trainer's connection to a certain Pokemon.

It could be a simple fashion statement. Abby is known for her unique style, and the hair tie on her wrist might just be another part of that.
