Sorry about that. The missing line is:
a[zeros([5,5]),:,b,c].shape
That is, your '0' is being broadcast into a 5x5 array to match the shapes of b and c. That is why the two forms you give are not equivalent. As to why you get that exact shape, I'd have to peruse the fancy indexing docs to figure it out -- things are a little weird when you use multidimensional indexing.
