Reflect works with the most recent full backup set in a folder. If there is more than one backup set in a folder, the older ones are ignored with regards to adding new incremental or differential backups to the set. Since only the newest backup set is used by Reflect, the name of that full backup will be used in all incremental or differential backups made after that full backup is created.
You can control things a bit by putting backups in different folders using different backup definition files for each. That way you can have multiple active backup sets - each in its own folder - doing different kinds of backups or backing up at different intervals, etc.
You can also move older backup sets to a different folder - however all the file names for a backup set will have same root name.
I do not exactly understand your question or at least the situation. But I hope that the above allows you to answer your own question.
