Can you send materials between two assembly lines?

Ok aswered this my self. However there is a nice big. If you send meterial throug a transporter to another assembly line and stop it again. The other end will keep spewing out the same materials continuously. Nice way to double your materials.

I found a similar bug, I deleted my transporter input on one assembly line so I could remodel that room for bulk circuit producing. But the lasers I was crafting there before kept coming out of the output in another assembly line. So even though I'm not making lasers anymore, I still produce them anyway. If I change the number on the output or pause it stops, but if I change it back or start again it continues.
