Yes, I did find that more than one or three instances of the WinUAE software was running. But if that was the cause of things falling apart, it would have been for something like that - or none visible even.... the cascading thing might relate to the executable running in multiple instances because of that command line. Some programs offer settings to control that and only allow a single instance of them to run at the same time (think Rainmeter not spawning another instance when ran with parameters from the command line, if it's already running), which would normally fix the said issue.
The usages would likely have been, in practice, not often. but I suppose finding out early is better than days or even weeks of multiple instances hovering in the background, wrecking an entire drive, or more than one even.
There was no listed use like I was trying and several relatively recent posts mentioned this idea, but the actual usage was completely different.
Word to the wary: Just swap virtual disks rather than shortcutting like this. WinUAE would have likely by now have made room for that if it was useful.
