the :global command takes all following commands and executes them for all
matching lines. So what you are seeing here is that :global marks both for
further processing and then prints the first line and stops redirection,
then prints the second line and again stops (the already stopped)
redirection. Effectively you are telling Vim to only capture the first line
that matches the pattern after :global.

No, the output is not what you expected. Vim only captures the first line
and puts it into the buffer twice.
