That's exactly written in here:
http://wiki.osmfoundation.org/wiki/License/Community_Guidelines/Horizontal_Map_Layers_-_Guideline

"For example, if there are restaurants in the OpenStreetMap layer and you
add additional restaurants in another layer, but you include only those
restaurants not present in the OpenStreetMap layer so that the restaurant
layers will complement each other, then the layers for this feature are
interacting and the restaurants added in your non-OpenStreetMap layer must
be shared."
