Think of this command as being interpreted from left to right.
command:   array[0[1]]

array[ ... now what do we index?

0[1] -> this doesn't work, it raises an error.

Whereas this:

command:  array[0][1]

array[ ... what do we index?
0 ] -> we index the first item.

so now we have this:

command:  ["0.0","0.1"][1]

["0.0","0.1"] [ ... what do we index?

1 ] -> we index the 2nd item.

so now we have this:

"0.1"
there are no more commands, so we stop here.

Hope that made sense,
