Thanks to all that replied. I've been puzzled by this for about nine

Towers that come down to a single point are preferred because there
is no side stress on the base or the bottom of the tower. If each
leg were to come down to the base, any imbalance would be felt on a
single SMALLER and WEAKER point (the tower leg), stressing that
point.
