It looks to me that the line is indicating how Levia and Behemo present each other as twins.

In real life, twins have to be born one after the other; one of them is older by a few minutes as a result. If, for the sake of ease, they present as twins Levia probably presents herself as older and Behemo as younger. Maybe even just because she's a lot more precocious than Behemo apparently is.

In short yes, it looks to me to be an empty clue.
