foo[a..b] means a bus consisting of bits a through b of bus foo.

In this case, Mux4Way16(sel=sel[0..1], ...); means a 2-bit bus made from bits 0 and 1 of the chip's sel input is connected to the Mux4Way16's 2-bit sel.

The bits match up from left to right, so if you use foo=bar[1..2] the the connections would be
    foo[0] = bar[1]
    foo[1] = bar[2]
