Can a double oxidation phenomenon generate an electric current?

An unusual battery is proposed in the experiment below. The particularity of this cell is the fact that both electrodes (formal cathode and anode) undergo oxidation phenomenon.
The experiment is very simple: put a piece of Fe and a piece of Zn in a sulfuric acid solution and connect these pieces of metal to an ammeter.
Although both metals are oxidized, an electric current is generated in an external circuit.
The detailed description of the experiment is presented at

A video is posted too, showing that bubbles of hydrogen develop at both metallic electrodes.
It cannot be accepted that electrons are generated at both electrodes and these electrons are traveling in the external circuit in opposite directions only for the sake of traveling...meet each other, greet each other and continues on ...
explanation?
You can perform the experiment in the kitchen using same metals and a acetic acid solution (vinegar).
