I linked to the Selle SMP U.S. patent in my post, and it explains the reason for the eagle-beak nose. I really hoped I wouldn't have to spell it out. Figures 9 and 10 are explicit enough so that some here may be offended, so rather than me posting them, you can just look at them in the patent document.

Explanation of the nose configuration from the patent document:

Lastly at the front part of the saddle 8, 8’, where the seat of the pelvis terminates, are the sections 9, 9’, sloped downwards in an eagle-beak configuration on a non-limiting angle of 30° - 45° for the racing saddle and a non-limiting angle of 75° for the touring saddle, as can be seen in FIG. 2. At the front end of the saddle the two sections 9, 9’ unite in a substantially semi-circular form with a diameter of approximately 4-3.5 cm to maintain the two portions, 1, 1’ united at the front.

Such a strong slope of sections 9, 9’ FIGS. 9, 10, prevents any crushing of the testicles, in the case of men, and the clitoris, in the case of women, when the saddle is in use, in compliance with the above-mentioned scientific urological research surveys.

Moreover, this also prevents the compression of the body of the penis, the deep dorsal artery and vein, thus maintaining normal blood flow.

The parts 9, 9’, which on the racing bicycle saddle are sloped downwards at a non-limiting angle of 30° - 45° are of considerable help to the athlete during the final sprint, or during timing races, at the moment when he moves the pelvis forwards, to provide a minimum support for the gluteus muscles, thus preventing all compression in the anus and in particular, on the prostate.

For me, function and comfort trump aesthetics every time.
