If someone needs to be overly organized I would be more likely to assume they are just on the ASD now, but I definitely remember people joking about OCD like you're saying. I have AuDHD (high functioning autism and ADHD) but that wasn't in the DSM until like 2014, so as a kid I just got the ADHD diagnosis. Now it makes so much more sense why I feel like Dr Jekyll and Mr Hyde sometimes. My autistic traits desire organization and cleanliness but my ADHD is good at "filtering" the mess out until it gets REALLY bad. Then I go into a cleaning frenzy ala old lady Sophie trying to clean Howl's castle. Sadly I don't have the grit of Sophie so I end up getting burnt out and being unable to clean anything for two months.
