Items going the wrong way through Sorters when using Alt+MMB

Note : this is clearly a duplicate of this report but since it's tagged as outdated, I publish the issue again here.

The setup is simple, two Containers separated by one Sorter (and a battery for the sorter to work):

The Sorter configuration is the default one, an empty blacklist:

Inventories are set as follow:

Containers and Sorter just have enough room left for 37 Steel Plates each. I try to deposit 200.

When I deposit them using the button in the menu, it works as intended:

The Sorter blocked the way to the red Container, as it should.

Now if I get back all the plates and try to deposit them using Alt+MMB, here's what happens:

Plates were distributed all the way through, seemingly going the wrong way through the Sorter.

Now, if I get all the Plates back and try to deposit them via the red Container, everything works as intended when I use the menu:

But if I get them back and deposit them using Alt+MMB...

Now it could not go through the Sorter, although it should have.
