i-134 Joint Sponsor - Separate Forms?

[Kürbis&Tannenbaum 20]

We recently received our NOA2 and were trying to prepare all the consulate documents ahead of time. I do not make enough $ to be the sole sponsor, so we will be using a joint sponsor. We will be using the Frankfurt Consulate in Germany. I am very confused about how a joint sponsor works for the i-134: do they need to fill out an entirely different i-134 then sign it, or do I just print out two of the same i-134's that have MY information and have both my signature on one of my i-134's and a signature on a second i-134 from the joint sponsor? Which is it?

 

 

Here's from the visajourney FAQ, but the writing is awfully confusing.  Any help is appreciated!

Hello, does anyone have any ideas regarding our question? We don't want to file I-134 incorrectly, as we already got so far in our visa process. You would really help us a lot if you gave us your advice on this topic!   Many many thanks!
