Because currently the Nokia HERE service which provides us the AGPS feature receives the list of available access points and only the cellular tower that you are connected to (while, ideally, it should get the list of all visible cellular towers). With a single cell tower triangulation is impossible, so we have to rely on the list of visible WIFI APs (which can only be retrieved if WIFI is on -- not necessarily connected, but at least scanning). Note that I haven't access to the Nokia HERE implementation (it's a closed binary), so how it actually works is just based on my speculations.
