For example, the definition given from the OALD for pronoun is the following one:


  a word that is used instead of a noun or noun phrase, for example he, it, hers, me, them, etc.


If I would rewrite it as the following, would the mean change?


  a word that is used instead of a noun, or noun phrase, for example he, it, hers, me, them, etc.


If the meaning doesn't change, are there other differences between those phrases? Is this just an example of using the Oxford comma, or is there something different/more?

I am asking because I rephrase a similar phrase, and I was said it was more correct without the comma.
