did the senshi know the starlight's identities from the star? (manga question)

Okay. So at the end of Stars 1, Iron Mouse attacks the Music Hall. The Three Lights make their escape and the Starlights arrive to rescue the Senshi, which surprises them. In Stars 2, the Senshi are discussing what happened and Haruka mentions that she felt the power of the stars from the Three Lights. They don't know if they're allies or enemies, although they did rescue them.
Okay...but it was the Starlights that did that and it was the Three Lights that disappeared.

Later on, when Seiya is singing to Usagi, she understands what Haruka meant. She also feels the power of the stars from them.

Can anyone help me here?
