Radiation angle vs turns count in a coil

I was discussing the construction of a screw driver antenna, and an off hand
remark was made by a fellow ham. "Wind the loading coil 8 turns per inch
for local and 10 to 11 1/2 turns per inch for DX as the angle of radiation
changes"

Can someone explain this to me?
