I found the following in http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/index.html?pcs.html.

The definition DATUM are mixed up between 102100 (3857) and 102113,
since DATUM for 102100 should be using a sphere vs. 102113 should be using pancake.
(the same thing happens for 3857).    3785 is gone from the list.

If you look at the DATUM section, 102100 is using a pancake but 102113 is using sphere.

Can you clarify?
