This allows an app to know when a set of drops are coming in a grouping of some sort (for example, a user selected multiple files and dropped them all on the window with a single drag), and when that set is complete. This also adds a window ID to the drop events, so the app can determine to which window a given drop was delivered. For application-level drops (for example, you launched an app by dropping a file on its icon), the window ID will be zero.
