No. The page makes several statements about Eevee evolving again. While I can imagine evolving Pokemon would dispel a red energy from their bodies, Ninfia is standing in a grassy field where the background was dimmed for the animation. You can see the ridges that make up the blades of grass around Ninfias ankles if you look a little harder. Now why would they place a picture of a pokemon evolving in the field? Normally they evolve in a blank area with little to no background or atmosphere so as not to distract the eye from the evolution. It's most certainly an attack, unless Game Freak dun' gone crazy.
