They're probably just wrong. The page may have been deleted and the
redirect entry not, for some reason. This sort of thing happens with
denormalized data. *In theory* everything is in transactions, so it
shouldn't happen, except when they aren't and so it does, or they are
and it still does somehow.
Thanks Aryeh for the explanations. Now it makes sense i.e. I should take
these numbers with a pinch of salt, because there might be errors in the
Wikipedia Database itself :) .
