I don't understand the 90 days part. Why would someone discontinue the medication that controls their symptoms?
I have ADHD and take Adderall, and plan to pursue a recreational/personal license next year.

"Rare but severe side effects of Adderall can include emotional instability, psychiatric disorders and cardiovascular events. Adderall misuse can lead to seizures and death."
There are plenty of medicines that warn against operating motor vehicles or heavy machinery, off the top of my head some blood pressure meds like Losartan and HCTZ because they can make you dizzy/prone to blacking out. I imagine there's similar logic here for pilots.
These bins are arbitrary and dosage matters. It would be perfectly acceptable for the FAA to require 3 months of usage, at a specific dose, wherein a pilot is stable on their meds and an FAA doctor (which they must visit anyways) approves them. You can get a good idea of risk factors and stability by doing this.
