Jeff, I seem to remember Randy and multiple names for a very long time.
Not sure that was a "change".

What did change is he likely got tickled pink at Thor66 getting called Mad Corgi, and channeled a lot more into that user name.

There could be a lot of different possibilities though.
I went through a period of working days and a half, lost a lot of health.
It did make me less social, less energy to invest in the people around me.
There's a level of investment that if I can't meet I'd rather not be out in a social setting.

The multiple names were likely to protect himself from cancellation.
Signing up with a name that could be traced to one yet loving to troll is a recipe for a second name.
Once two, why not three...
