That's pretty much true.
The two moons orbit the planet at the same speed as the planet orbits the sun. (88,065 days.)
As a result, one planet is always between the sun and the planet, but the other is always on the side of the planet facing away from the sun. That is why he has an eternal solar eclipse. (However, the planet is not big enough to completely cover the sun.)
In addition, the moons are tidal locked to the planet. As a result, they always turn their same side to the sun.
In the case of the moon facing away from the sun, this does not play a major role, but the moon on the side facing the sun always has a dark side.
I got the idea through a science-fiction novel that claimed that a tidal locked moon always turned the same side to the sun. That is normally not possible. Only in this way.
I've only expanded it a bit by adding a moon that is always in the shadow of the planet.
