mixing google maps api v2 and v3 possible?

Question

One question linked an interesting example of mixing API v2 and v3!. Look at the code:

function initialize() {
  if (GBrowserIsCompatible()) {

    // Create and Center a Map
    var map = new GMap2(document.getElementById("map_canvas"));
    map.setCenter(new GLatLng(37.4419, -122.1419), 13);
    map.addControl(new GLargeMapControl());
    map.addControl(new GMapTypeControl());

    // bind a search control to the map, suppress result list
    map.addControl(new google.maps.LocalSearch(), new GControlPosition(G_ANCHOR_BOTTOM_RIGHT, new GSize(10,20)));
  }
}
GSearch.setOnLoadCallback(initialize);

The map is apparently in v2 but the code new google.maps.LocalSearch() is v3!

How is this possible?

Maybe it's not really API v3. I thought it could be deprecated Local Search API that worked within API v2, but it is not: in this API the object is google.search.localSearch while here it is google.maps.localsearch ... I'm totaly confused.

That example only uses v2, not v3 at all. The v2 API does optionally expose everything under google.maps (for example google.maps.GeoXml) – most people just use the 'G' naming though.

There's also a difference between google.search.LocalSearch (which lets you query Google for local search results) and google.maps.LocalSearch (which is a v2 control). Since both APIs are deprecated, I'd avoid both!
