If I understand the code correctly, $h{/regex/} = $value updates $value 
in all the entries whose key matches /regex/. That's right. But 
$h{/regex/} returns just one value, and which one is undefined because 
it is the first one in hash order among the ones whose key matches 
/regex/.

I think I would expect a list from FETCH, or at least a list if 
wantarray.
