This tool allow you to easily grab the geometry resulting from a spatial geometry calculation (buffers, intersections, unions, ...). It was made to provide an additional1 way to spatial queries within ArcGIS feature services as shown in the following video.
(1) Feature services have a "distance" parameter that allow you request the service to make the spatial intersect with the buffer on the backend in your behalf.
The service used on that video was Current Weather and Wind Station Data that contains +5800 weather stations.
Service url: Current Weather and Wind Station Data service URL.
The response of the query shown on the video was:
