Weight of tamdem versus two solo bikes

A question posed to the New Scientist's 4 July issue posits
that multi-seat bikes have a total weight advantage over
solo bikes (per seat), asking at what seat count the weight
advantage per seat fades away.
Initially, I thought the premise of the question mistaken,
but now I'm curious: Is it true that a modern tandem weighs
less than two solo bikes of the same total carrying capacity?
The illustration that accompanied the question is of a triple,
which I've never seen anywhere in the wild and was probably
chosen for its attention getting value. It's on page 56, alas
no weblink is offered.
Thanks for reading,

I don't know.
My old friend Lenny Preheim (Toga Bike NYC) owned a six
seater which he rented for parades and such. It was built
more like a steel bridge (including prestress arc shape)
and weighed like one too with motorcycle type rims and tires.
So I agree there's some limit beyond which the vehicle
weight per rider becomes deleterious to efficiency.
