Yeah, that one pony saying the Young Six were glowing like the Elements could mean that - but more likely, she was talking about the glowing itself, either reminding her of the glowing of the trinkets in the Tree of Harmony (since it's possible there was a class field trip out to where the Tree of Harmony is) or else she saw the Mane Six use the Elements before, and it reminded her of that (the glow when they activate them).

At this point, it's purely speculation.
