Why would an ALU's ouput change asynchronously in response to input changes?

Wikipedia states "An ALU is a combinational logic circuit, meaning that its outputs will change asynchronously in response to input changes."

But, the definition of a combinational logic circuit is: "combinational logic ... where the output is a pure function of the present input only."

If the output of a combinational logic circuit is purely determined by present input, is Wikipedia stating that it's asynchronous because of the time it takes for an electrical signal to travel through the circuit (~light speed right?)?
