Phobos-Mars L1 point?

I posted this in another discussion of Phobos, but it probably belongs here:

I keep seeing quotes (E.g. Wikipedia, but other sources also) that Phobos' L1 point is 2.5km over Stickney crater. 

But shouldn't L1 be directly between the moon and Mars?
And Stickney is on the "Western" limb of Phobos as seen from Mars, right?

Could it be that they are actually thinking about L4 ?   Or am I missing some aspect of the orbital mechanics involved?
