He didn't say "the meaning of the word Satella" in the sense of the pseudo-analysis of the name (which will vary depending on where you get it from and it often applies to a lot of people much like other "horoscope" and such)

He meant why THAT name? Stella, "Star".

More than likely linked to why all the members of the cult have star-based names. (6 bishops, Al, Subaru and Shaula so far)

She's also the only one of the witches to not have a major myth-based name. It likely isn't myth-based at all.
