I suppose it has > something to do with how lazy-seqs work (another mystery for me). A lazy seq is basically a sequence of the first element and a "thunk", where a thunk is a function without parameters that knows how to calculate the rest of the lazy sequence. When you call `rest' or `next' on a lazy seq, that thunk is called computing the next item (realizing it) and the next thunk, which again knows how to compute the rest of the seq. So although your lazy-seq function looks recursive, it's actually not. Any thunk closes over the previous value in the seq, so it can be called independently. By the way: that's explained very well (with images and stuff) in The Joy of Clojure, in case you have that handy.
