google-mirror-api - What gets shared?

Question

Something is unclear to me with regards to the share action.

Does the sharing endpoint (google+ contacts, or other subscribed glassware) receive the timeline item with whatever it contains (html, attachment...)?

Example:

If I have this item in my timeline...

  {
   "menuItems": [{"action": "SHARE"}],
   "html": "<div>a beautiful HTML card</div>",
   "location": {
    "latitude": 40.702587,
    "timestamp": "2013-05-20T19:22:56.164600",
    "displayName": "KLOMPCHING GALLERY",
    "longitude": -73.98926,
    "address": "111 Front Street"
   },
   "id": 42004,
   "isDeleted": false,
   "kind": "mirror#timelineItem"
  }

...and I click on share: the sharing endpoint would receive this same JSON object?
