ELI5: Why do some judges in criminal cases sentence a defendant to "two life sentences"

If you're serving a life sentence, then you're incarcerated for the entirety of your lifetime so what is the point of sentencing sometime to two life sentences? Is it just for effect? Is there any practical reason for it?

This can happen when there are multiple counts of a serious crime involved.  If some of the counts happen to be overturned on an appeal, the sentence will still be life imprisonment due to the other counts.
