Isn't that a bit of an odd wording though. Of course if you only buy the horse without the cart you have to build the cart, making "your" solution more complicated. But you still bought the "simpler" solution i.e. the horse without a cart.

Complexity may be the wrong word, but what I mean is surface area for bugs you are responsible for.

I also question whether you really bought a horse in this analogy.
