Wow... is this for real??? Where did you get this picture from?
If this is for real we can really rejoice for Dorje Shugden is a Buddha and would not be bias as to what sect or school you are from. I believe DS would protect and bless all practitioners as he is Manjushri in nature so there is no doubt he would help anyone who requires his help
However, this is an interesting article if anyone can verify, quote from
http://truthaboutshugden.wordpress.com/2010/03/08/a-sakya-tale-part-three-dorje-shugden-the-great-compassionate-one/In 1871 Kunga Nyingpo had his own son, Dragshul Trinley Rinchen. Dragshul Trinley Rinchen grew up to become the 39th Holder of the Sakya Throne.
In his autobiography, this lama explained that his father Kunga Nyingpo was Avalokiteshvara. In order to prove this, he recounted the story about Mahasiddha Pema Dudul and Trinley Rinchen detailed above and then wrote
The Dharma Protector Dorje Shugden Tsel definitively is Avalokiteshvara. The Nyingma Tantra Rinchen Nadun says “The one known as Dolgyal is not mistaken on the path to liberation, he is by nature the Great Compassionate One,” which establishes this by scripture.The Great Je Sakyapa Kunga Nyingpo is well-known as an incarnation of the Arya Lotus in Hand (Avalokiteshvara). The Arya Lotus in Hand definitively is none other than the Lord of Mandalas, but provisionally by assuming the manner of a tenth level bodhisattva he simultaneously sports billions of superior, middling and inferior emanations to accomplish immeasurable benefit for beings, such as setting them on paths to the higher realms and liberation.

Thus in order to show that his father was Avalokiteshvara, he set out to show that his father was well-known to have been an emanation of Dorje Shugden, and then demonstrated with a quotation from Nyingma tantra that Dorje Shugden and Avalokiteshvara are the same person.
