I don’t get what you mean but what it implies to me more is
Smolder: Loyalty (or whatever it’s third run name will be like @Eclipse Wing said the names changed from the pillars to the mane six it’ll probably change with the student six)
Yona: Honesty
Ocellus: Generosity
Silverstream: Laughter
Sandbar: Kindness
Gallus: Magic

The glow also shows that to me, Sliverstream has a pink glow Pinkie is pink, Yona has a orange glow AJ is orange, Gallus has a purple-ish glow Twilight is purple, Sandbar has a yellow glow Fluttershy is yellow, Smolder has a blue glow RD is blue, Ocellus has a white glow Rarity is white y’know

Given that the Elements of Friendship are like the spiritual successors to the Pillars of Equestria, but don’t actually carry the same titles (“Hope” became “Laughter”, “Strength” became “Honesty”, etc.), I would argue that the Student Six aren’t actually inheriting the Elements as we know them but something new.
 
In the days of the Pillars, Equestria needed heroic aspects and for Twilight’s generation, it needed bonds of friendship. Now that these times have passed and those aspects have become ingrained into Equestria, it would call upon the next generation to embody new concepts, loosely tied to those before them but not quite the same.

I like how they didn’t get the exact same element people may have expected to give them. For example, I’m sure some fans would have given Silverstream the element of laughter because she (and by an extention Princess Skystar) are happy and joyful and are sort of Pinkie Pie expies.

Okay, this is a pretty neat observation. Good show.
