No [2] means that a 2nd one exists which would be true if a 3rd one existed etc.

The full dataset picks up instances where there is more than one
duplicate so I can verify the above interpretation.

Having said that your offering although more verbose is superior
semantically as really the best way to write this is something like
(and I am pleading the fifth on the syntax here)
exists(key('person',@href)[2]) but then you look at that and you
realise or can argue (I think) that what I wrote is an abbreviated
form of that anyway.

I suppose a guru could tell whether they are semantically identical
and whether the one abbreviates the other.
