    To be more (irritating and utterly) correct, an ‘original’ chroma keyers output is exactly this.
    The old school boxes only outputted a b/w signal, like your example.
    That would be used to feed a switchers key input, so you could choose your fg and background.
    In most cases, fg is the same source as the image used to extract the key, but there is total freedom in choice for that.
    Even modern switchers allow for any bus to act as key source, and two channels for fill / bg.
    The same is true for most software, but you have to force it to output the key signal only. (Mostly used for checking the matte, not so in your case)

    Btw, the credit roll on the BBC tv series ‘Bottom’ was done the same way, and of course lots of James Bond movies have the key two different sources with a nice woman in the leader.
    (don’t forget the Kiki wipe…)
