OK, I'm impressed. After speaking with the Sirio engineer and confirming this confinement and replacement of out of phase radiation, I wondered the same thing and built a model. The weather here has been poor the last few days so I haven't run any field tests yet. Earlier test where I extended the radiator and radial length showed the gain began to drop as the radiator went past .82 wavelength with radials just over 1/4 wave. It is quite possible that there just may be a null in gain when extending these lengths before a second peak in gain is seen fully extended. We shall see soon enough.
