When I overlay a bluescreen foreground video over a background video,

[foreground](a),colorkey,(b)[fg];[background][fg]overlay,(c)
I found here an example for (c) but I doubt that this makes sense:

Why do you doubt that it does make sense?
I doubt that (c) is the right place because at position (c) the despill
filter also affects the background video, which surely doesn't have any
contamination from the bluescreen.
