It doesw radiate at right angles of the axis but for maximumum
radiation of a particular TYPE then the resultant maximum radiation
vector is between ten and fifteen degrees from the ninety angle.
The total radiation is the same at right angles as to that when tilted
10 degrees or more from that angle.
If you play with the angles on any computor program including
EZNEC I suppose, using a wavelength radiator, this is readily seen

Below is table of free-space field values for the radiation of a vertical,
full-wave, center-fed dipole, from the horizontal plane to +/- 60 degrees of
elevation, using the "resultant maximum radiation vector."

Note that an elevation angle of zero degrees is at right angles to this
radiator.

Please explain how this validates the theory stated in your quote above.
