Handling of multiple inputs at one output

[pherrman1]

How are the outputs handled if there are multiple inputs next to the output?

E.g. there is a mine next to a deposit which produces x resources. At the output field of the mine there are 3 conveyors with input fields next to the output field of the mine. Do the conveyors share the resources or does one get (randomly?) all the resources?

The interactive modell at "https://profit.phinau.de" gives an error if I try to connect two conveyors to one mine, is this correct? (see example)

You can't connect an output (egress) to more than one input (ingress), but the challenge description failed to mention this. Updated, thanks.
