Same as the blue/gold version that also was available for both.
This recolor is obviously blood elf/kael'thas vibe. It will be glorious being a blood elf with this, there is no contest there.

I mean, I think we can safely say, the whole design and with color scheme, is exactly like Kael. The other recolors of this, were for fun. This is the real deal. Hopefully they will eventually do more with cloaks in the future. I would love a over the shoulder type of cloak with Maiev like physics or even better like Lor'themar, who uses a better cloth system even. You are right, alliance won't be able to match this with the Sin'dorei armor, which fits perfecty. So it already kinda makes it, more horde/blood elf orientated. There is no better match in game for these shoulders/headpiece.
When ever I get this in my hands, it will be hard to switch if off. I knew the moment it was datamined, that this would match and it sucked the blue one was given first instead. Actually excited for something so small.
