the /g modifier makes sense only if you are matching the same string multiple times
Not entirely true. In scalar context (such as when it's the conditional of a while), it's about repeated matching. In list context, it will do the global match and return all the captures at once. 
$_ = 'pig dog goggles';
my @hits = /g/g;
print "@hits\n";
