As far as I can tell, the idea that these were other personalities didn't enter Chloe's brain until a crisis counselor (I think) told her that having a dialogue in her head wasn't normal. (It was.)
Despite that, Glass the fairy says she remembers fronting at the age of three. Chloe treats her alters like they're all fully formed spiritual protectors rather than personality states. She really just writes the rules as she goes. IMO, it's closer to having metaphysical, magical-thinking based time with friends, feeding into each other's delusions Heavenly Creatures-style than it is a recognized version of what any competent mental health professional would call DID.
I think that Chloe really got into things when her YouTube channel took off. She had liked the angst-flavored LARP'ing, cast of fun OCs look of the DID community before, but now she was actually getting an audience. Despite her diagnosis being brand new, she presented herself as an expert. And people believed it, because the DID community is already conditioned to group-think and biased towards anything that reinforces their magical thinking. That Chloe says she's an expert and copies and pastes sources she hasn't read is enough. They aren't going to fact check her anyway.
So Chloe doubles down on the DID, becomes more immersed in the ridiculous community. It's scratching a lot of itches for her by giving her attention, money, and feeding her martyr complex. So I think in those early days she was especially scrambling to convince herself of her own diagnosis, filling in any space she could with "evidence." Like, "Oh, I was happy here. That was an alter. Oh, I was depressed here and my dad said that didn't sound like me. Ect." She's realizing her hobby could become her career while she's still in that fun faze, getting excited by every tiny synchronicity. Now she can't keep the fiction she wrote for herself straight or answer questions about its huge leaps in logic.

"The identity problems that occur
in personality-disordered patients may occasionally be misdiagnosed as a
symptom of DID."
"Inexperienced clinicians may also confuse a patient’s investment in
a metaphorical “inner child” or similar phenomena with clinical DID."
"
patient’s desire to have a more “interesting” or elaborate disorder, resulting
in the patient coming to believe that he or she has DID..... patients with this kind of
pseudo-DID tend to be characterized by an
enthusiastic embrace and display of their “identities” that is contrary to typical DID patients’ pervasive
pattern of disavowal—of dissociated aspects of themselves, of overwhelming trauma, and of the diagnosis of DID"
It can be helpful to use the terms that patients
use to refer to their identities
unless the use of these terms is not in line
with therapeutic recommendations and/or, in the clinician’s judgment, certain terms would
reinforce a belief that the alternate identities are separate
people or persons rather than a single human being with subjectively divided self-aspects.
"elaborate systems of identities are multiple traumas, multiple perpetrators,
significant narcissistic investment in the nature and attributes of the
alternate identities, high levels of creativity and intelligence, and extreme
withdrawal into fantasy, among others. ----->edit is that a fancy way of saying LARPING OC's???
