Yes this explodes the geometries and retains the original attribution.

I've not used this tool but are you aware of this sampling tool? Worth a look.

There is no connection, the iterator controls the whole model and is generating a variable called value which you use inline substitution to make use of it.

comment Upstream to a river and tributary of a river - What is the underlying difference
Your scenario can exist in a vector network. It depends upon how you define "connected". If connected is a polyline that connects at a node but you are not interested in its direction of flow then you can have the scenario where two streams are touching at the catchment boundary and are flowing in opposite directions. This is often referred to as a "saddle" and is usually a flat wet marshy area or a small lake.

Just tried your tool, very slick! Apart from it crashes if I try to write to in_memory :) This is the sort of useful tool that should go on the ESRI code gallery for a wider audience.
