It has to do with it being the same operator; you're effectively starting a
new glob with the second scalar(glob '*'). I assume there is some context
assigned to the op code itself. Consider a similar example to your for
loop:
{
my $file = glob('*');
last unless defined($file);
print $file;
redo;
}
