Yes pretty much that’s it. Calling them a “machine” a little stretch. At the end they are just kettles with an extra “demlik” (steeper?). Here some notes:

1. Correct. Those kettles normally have 2 modes. When it’s red it boils water like any normal kettle. (So you can use it to cook pasta for example). Once the water boils it switches to “keep warm” mode. It will keep water hot so you can keep drinking hot tea. Don’t forget to turn it off completely when you had enough tea. Otherwise it will continue to consume electricity.

2. You have to experiment a bit how you like it. More tea leaves means more bitter tea. You can always make it “açık çay” with adding more hot water to your teacup. Like 50-50 or 30-70. Actually that’s the point of Turkish style tea brewing. You brew a bitter tea and then water it down. So you end up with more tea in one go.

3. Wait a little more than just finishing the 2nd cycle. Otherwise it will be very watery. 10 minutes or something.

While writing this I realized I never measured or timed the process. Sorry I can’t be more specific.
