This command is too odd. Just
echo (g)
does exactly the same. You must read `man zshexpn`, section “Glob Qualifiers”: `g` qualifier stands for “files owned by group ID” and expects group ID as an argument and `G` qualifier is like `(g[$EGID])` (assuming parameter expansion works here (it actually does not)) and takes no parameters.

Do `setopt nullglob` or `setopt nomatch` and you will see that this is *not* OK because `(G)` matches nothing. The only reason this may echo `(G)` is that you have enabled POSIX shell-like behaviour which substitutes glob pattern with itself literally if there are no matches.
