Alicorn Twilight new coat of arms.

I wonder if anyone noticed it in the last episode. But the symbol that appeared in the sky after Twilight ascended, and the symbol on the flags that those white mares were carrying had six small stars surrounding the main big one, unlike Twilight's cutie mark, which only had five small stars. Do you think it has any hidden meaning behind it?

I'm pretty sure her cutie mark hasn't changed. Although it was difficult finding a clear shot of it after her transformation, because it's almost always covered either by her wings, or by her ridiculous dress.
