HVDC back to back system

    The above diagram is for HVDC back to back system. My question is why do we call it back to back system?

    Could someone please help me here?

    It's a sports metaphor - like two games, back to back.

    In this case it is because you see an AC system connected at one end, and another at the other end: back to back.

    Could you please explain it? I am guessing "the two games happening immediately one after another. Correct?"

    The simplest configuration is the back-to-back interconnection in which two converters are on the
    same site without a transmission line.

    Could someone please indicate the similarity between the bold part of the above sentence and the HVDC back-to-back system diagram above?
