She's not the "Third member" necessarily. I doubt she's the leader, but the characters don't have to be drawn in order of the acronym. They could just as well (more likely even) be grouped by partners, regarless of the team name. Like how Pyrrha, not Nora, goes next to Jaune.

Not saying she isn't the third, but there's no saying she's not 2nd or 4th.
