There is little point changing one page when you are running a bot job to change many well sort of but the whole point of preferring MMM over MMM was because of the need to abbreviate for confined places and the use of three letters for ascetic reasons in tables the dot obviously takes up one extra space In the case of references in a reference section there is no reason to prefer MMM over MMM because the space is not confined so if you are going to change them then change the to the full month which is in line with the intent of the instructions
