Indeed.

The idea is that -S/-N documentations say that it is just a shortcut for
-b, but the explanation (eg --help) is too far away.

I would suggest to make it even shorter, see attached:
query mode (-M) should be specified before any transaction scripts (-f,
-b, -S or -N).
I'm wondering whether it could/should be "any transaction script". My
English level does not allow to decide.
