Rules for applying source data when using the art history brush

Question

I am trying to discover if a Snapshot made with the History feature can be used by the Art History Brush on more than the Snapshot's corresponding layer.
So,  I have an image with a background layer and a copy of that background layer - two layers.  I then make a Snapshot from the second layer and apply a fill colour to the second layer.  Next I paint on that filled layer with the Art History Brush.  Now here's the issue - having completed painting on that second layer I would like to be able to duplicate that second layer so it becomes a third layer and paint on to it with the Art History Brush using a new brush type but the same original Snapshot.  My experience so far is that the Art History Brush and History function will not allow me to paint with the original Snapshot on this duplicated layer.  In other words, you cannot paint on to the third layer using your original Snapshot.
Is this correct, please?  I had hoped that the snapshot I originally made would be available to use with the Art History Brush on any layer in your layer-stack but this seems not to be the case.  It will only work with the layer from which the original Snapshot was created.
I can of course create a new snapshot of the duplicated, painted second layer - now called the third layer - but this only enables me to paint with the image in the second layer (from which the second Snapshot has been created).  I want to be able to paint on to the third layer with the original Snapshot but this it will not let me do.
If anyone is kind enough to read through all this and follow my exposition I'd be really grateful to know if my understanding is correct.
Thanks.

If you don't make the new snapshot with the icon but with the palette menu, you will get a window with 3 options.
Try which of the three solves your problem.
Sorry, my  menu is in german, but you see the position.
