Another way of possibly looking at such a statement - the 12 and 24 - plays with Mercator Projection.
That is defined by the wonder of having spherical observation projected upon 2D presentation, where the horizontal 360deg relates to the vertical 180deg, giving a perfect square incorporating 360deg all over...if you realize how the two ends of the horizontal are actually the same meridian. Stellarium will offer the views for you.
Cylinder Projection just doesn't do it right.
Of course, that takes 'squaring the circle' to its true meaning...
