On the other hand, if you wind 1st layer from left to right, then bring
the wire back to the left side somehow, then wind the second layer again
from left to right there will be voltage difference equal to the
voltage induced in one layer. A great advantage! If you calculate
the interlayer capasitance (through energy balance) you will find
you the interlayer capasitance is 1/4 of the capasitance you did get
with the fist method!

Just to reply from experience-- Before I knew that neon transformers were 
available cheap, I rewound half of one that was blown.  I originally 
tried the technique mentioned above.  I did it so that the voltage 
between layers was even rather than increasing in one direction (right or 
left).  I used mylar between the windings for extra insulation.  The 
problem with trying to snake the wire back to one side was that it left 
me with a very lopsided coil.  The next time I wound one, I just went 
back and forth.  The results were much better.  Granted this was the 
first and second (and only two) times I did it, but if you are 
considering rewinding a transformer, it's much easier to go back and forth.
(Discounting any electrical advantages).
