You're right. Th proof is that at latitude zero each meridian is spaced 60 NM, the diameter of the circle.

Please coorect me if I'm wrong but I think that in Reed's Nautical
Companion -3 edition (it is what I have) in Section 3, p.133, one step of the
method regarding working with UPS isn't right.  Specifically, "...to
draw meridians of longitude with the spacing that corresponds to this
mid-latitude, start at the verical axis and count X degrees out along
 the
circle..." 

 I think you need to count degrees from the mid-latitude line which goes across
compass rose, W-E, instead of from N-S.
