Yes, 'Chained' takes the private action name. The whole chain creates a
publich path. From the docs:

  "The Chained attribute allows you to chain public path parts
   together by their private names."

Your problem has nothing to do with the PathPart attribute, the differing
Chained values are the matter. In your two examples, the PathPart
attributes don't even have different values.

Yes, 'Args' marks an endpoint and is implicit. You probably want a
CaptureArgs attribute here. From the CaptureArgs attribute docs:

  "Must be specified for every part of the chain that is not
   an endpoint."

Kind of :)
