:command -complete=custom with a glob()

I've been having an issue with a command completion function, particularly
with how it wraps around the ends of the matches. Normally after the last
match, the original text should be used before looping to the first match.
But when the function calls glob(), it no longer returns to the original
pattern, and instead loops immediately to the other end of the matches.

Am I just being stupid and doing something wrong?

Reduced case:

command! -nargs=1 -complete=custom,Test Test echo <q-args>

function! Test(ArgLead, CmdLine, CursorPos)
call glob('')
return "foo\nbar"
endfunction
