ORG with an omitted operand is fine as long as you understand that it sets the location counter to "the next available address in the current control section". This is why Gil warned of the hazard of a prior ORG. If someone - probably unrelated to and unaware of your macro - has previously defined a location beyond where your macro expands, a plain ORG will not "undo" your ORG *-4, but will move further forward to that highest previous location.
