It's farther away from Earth, but is not on the far side of the moon:

You...you do know the moon orbits the earth? So something beyond the distance of the moon from the earth will by definition be on the far side of the moon when the moon passes between the spacecraft and the earth. The sun. Mars. Jwst. All of them are past "the far side of the moon" even though technically the near side is sometimes looking at them face on.

That only means it's occasionally correct but usually incorrect.

Thanks. For some reason I had thought Webb is at the Earth Moon L2 point, instead of the Sun Earth L2 point. Not sure how I got that wrong, but I appreciate knowing the truth.
