Technically they are different maps altogether because they both use different channels depending on how they are used. So I wouldn't use them interchangeably unless you needed to because it won't look 100% correct. Most of the time though these maps tend to look identical in terms of what parts should be shinier and darker so that's why I decided to use it in this case.
