Commas can alter the meaning by modifying the grouping of words.

Explanation:

Here is one example:
[1]color(white)("XXX")I saw the twins, Alice and Josie.
versus
[2]color(white)("XXX")I saw the twins, Alicecolor(red), and Josie.

In case [1] I saw two people, namely the twins whose names were Alice and Josie.

In case [2] I saw four people, namely the twins and also Alice and Josie.
