Hmmm... OK, but they still won't be sharing the current equally.
The one that has the lower current-limit point will be at
its full capacity, while the other one will have a smaller
share of the load. At least, that's how I understand it.

I'm sure I've seen a note somewhere to the effect "do not
connect in parallel", but of course I've no idea where I
read that!
