This is how bash is supposed to behave.  Defining SYS_BASHRC makes bash
source that file just before it sources the bashrc file.

I'm not sure which manual you mean.  The bash manual doesn't say anything
about SYS_BASHRC, since it's a feature that's not compiled in by default.

The manual does have something to say about that:

        Bash  also  interprets  a  number  of  multi-character
        options.  These options must appear on the command line
        before the single-character options to be recognized.
