RegExp.prototype.exec behavior depends on global property. RegExp.prototype.exec behavior depends on the lastIndex property:
Let global is true and let I = If ToLength(lastIndex). ToLength(lastIndex) is the starting point for the search, so
Then if I>length then set lastIndex to 0 and return null negative numbers result in searching from 0.
