Yes, this is one of the reasons emissives are still beta. They work by drawing your entire player a second time without lighting using an alternate version of your skin that's just the emissive pixels. To avoid z-fighting, the places emissive pixels were on the vanilla skin are erased.

The way these are rendered has been pending a rework for a long time, likely via GL_POLYGON_OFFSET, but it's not something I've gotten around to.
