CRJ had a similar shutoff latch, but I don't recall anything like that ever happening. I think the CRJ latches had to be pulled up? Been a long time. Maybe a sleeve got caught?
I do remember that when I shut the engines down that I was meticulous about doing them deliberately and one at a time with a pause, to avoid developing any dangerous muscle memory that might bite me in the heat of the moment. After watching CA's grabbing both and shutting it all done in one smooth motion.

I also have lots of time in the CRJ... most of it in climb.
The locking mechanism to prevent shutdown from idle was a flat tab aft of the power lever (red tabs in linked photo below; CRJ and 604 virtually identical) which typically was lifted by the fingers while hooking the thumb over the power lever. That was more ergonomic than trying to lift that tab with your thumb.
Your buddy's theory sounds completely plausible. The PIC's wrist (or any other object such as an iPad or clipboard) could lift those tabs as the power is retarded.

Here is a video of the throttles being reduced while CA has hands on flap switch, and the cutoff handles being activated as a result:
