Not true.
There is always an angle and direction where the fields do not fully
cancel.

Funny, I don't see "fully cancel" anywhere in my posting.
I probably should have said "tend to cancel".

A free space vertical with horizontal radials in EZNEC
has horizontal radiation more than 40 dB down from the
vertical radiation. That's a high degree of cancellation.
