Correct. Copy-paste of a tool creates a copy of the modifier with a unique name, but pasting an instance does not—the new tool will have the
same modifier, not an instanced one.
It's behaving as designed. It's a matter of opinion whether or not the design is bad. Personally, I think the best change would be to make the animation spline visible in the Modifiers panel, although that would risk clutter. Maybe there could be an option in the prefs to turn it off. That would go some distance toward helping users understand what's happening while not breaking legacy comps and habits.
