The short answer is simple. Beverage antenna is really a transmission line with 
all proprieties of a transmission line, in one side is terminated by a load and 
on the other side by a transformer. The difference in speed of the signal, and 
the arriving wave  angle of incidence, on the in the open air wire, and in the 
second wire, that is actually the ground, generates a current that travels on 
the direction of the arriving wave. 
The wave near the ground interacts with matter (ground) and it is reflected 
back, the vertical component has a positive phase and adds to the incident 
vertical component and generate the current that travel the transmission line 
(wire+ground). The Horizontal component has a negative  phase and cancel the 
horizontal component and the result is no current is generated.
