Weird Recon cloak glitch in Lockdown...

During my match today in Lockdown, whilst my Heavy Plate Helm (incredibly underused) was equipped, did a really cool graphical glitch/bug or whatever.
Basically, when I went invisible mode, the outline of my character showed the outline of a 5* Volcanic/Ancient Plate Helm on its head, rather than my 4* Heavy Plate Helm. It was pretty cool, and I didn't even notice it until I saw the horns sticking out of the helmet outline. When I uncloaked, though, my helm is still its usual 4* self.
Does anyone know why this happens?

Basically what Gwen said. Lots of objects share the exact same model, just with different textures. When you go into recon stealth mode, instead of drawing the regular textures on your screen the game instead throws those out and instead paints the whole thing with the "ghostly" transparent style effect, including areas that were previously deliberately left untextured.

For example, Love Puppy Disguise shares the same model as the Chroma Mask just that it is pink and Chroma Mask is green.
Same could be said about Barbarous Thorn Shield and Dragon Scale Shield, if you look at the two closely, you can see the shape of them is exactly the same with different colours.
Could be that they used the same basic mesh and just rendered the horns invisible, much like the "chains" on the Levi Blade. Levi Blade and CIV use the same skin mesh, but the chains on Levi are invisible and only show in certain areas due to a visual quirk (most notably they can be seen in arenas). It is probably the same thing.
