it doesn't return the index, rather the element itself..

True. This is what I meant by confusing, without properly defining the variables at play, in this context, k is the index of the element of the ordered list, and not the kth smallest element.

Semantics, I agree, but confusing nonetheless.

Or in other words, how do we define k?
