The example (I) with 4 shorter solutions (h#1.5) might appear as showing the same content except the "wasted moves" by bLi. But these "wasted moves" make a change between the set-play and solution, opening a new dimension. That change gives the original dynamics to the problem and justifies the use of Lion for the idea. In the set-play too, the tries could be marked:
1...Bg2(Bc6?,Rc6?)etc.;1...Rc2(Rc6?,Bc6?)etc.
Example (I), h#1.5 4 sol.
W:Bb7,Rc7,Bf4,Kg3,Pb2
B:Pb5,Bf5,Rb4,Pd4,Pg4,Pb3,Kd3
In such specific type of problems, moving of the most important piece in the twin is rather unpleasant. The fact that both set-plays and both solutions are not possible from the same position, reduces the charm of a beautiful idea.
Mereith (5+7) would compensate for the twinning a bit.
wSb3 looks as the unique possibility.
Still, wK on f8/e7/d6 would spare wPa6.
