The first blond is Grindelwald; the second is Draco. Draco did take Dumbledore's wand from Dumbledore's hand in that that Draco cast Expelliarmus. Draco did not take the wand for himself, and he did not physically take it or touch it, but the second sentence you quoted was only supposed to say Draco was the cause of the removal of the Elder Wand from Dumbledore. I was careful not to use the terms "prised" or "from his fingers" again so that there would not be this confusion, but perhaps I worded it badly. Thanks for your input.
