I'd say it's no information, since he is compelled to do so. Voluntarily 
condoning the insufficient call by bidding directly is disallowed.
To the contrary, the fact that North didn't bark, er, summon, would be 
information although it would seldom be usable, as there might be many 
reasons for it, as former posts tell us.

Note that, even if conventions over insufficient bids are disallowed, there 
are agreements that aren't conventions ...
If I had bid 2D over 1S, expecting it to be read as fit-showing, would it 
be allowed ? The reason for that meanng is that we have a general treatment 
(not a convention, unless I misunderstood the definitions) that "a new-suit 
bid over partner's competitive signoff, by a limited hand, is always 
fit-showing" and I expect 1S to be a signoff (the reason why North condoned 
1H).

You would most probably have scored the same had you disallowed West's 1H 
bid, but it's a nice story.
