Must've not been a very good 720p then. I've seen it and it's even clearer it's the same cross as the Templar's emblem, not a "thing that holds a bracer". I did some Shadows/Highlights on a 720p screenshot at 18:10 that should remove all doubts: http://assassinscreed.wikia.com/wiki/File:Templar_Embers.png

At that frame, and only that frame (near 18:10 time-frame), the cross becomes so clear and bigger as if the creators edited the frame itself just to say "Hey here's a clue". But still, just because he's a Templar doesn't mean he really did poison him... That's still up for subjective interpretation I guess...
