The thing to remember here is that the '=' indicates a wiring connection, not a value assignment. The names are not variables as understood in programming, rather they are the names of wires and I/O pins.

The name on the left is always the name of a pin in the part being used, the name on the right is always the name of a wire or pin in the part being defined.

If you are building the DMux which has the following definition:

CHIP DMux {

    IN  in, sel;
    OUT a, b;

and you had a part line

    Not(in=sel, out=b);

in and out are pins in the Not, sel and b are pins (or wires) in the DMux.

If you haven't, read the Hardware Construction Survival Guide.
