Can't tell you without reading the indictment, but it's a common practice to charge a crime under alternate theories. Many criminal statutes have different versions, like in Ohio Burglary can be by force, by stealth, or by deception. In some instances, you charge two counts, one by force (like forcing open a window) or by stealth (sneaking through an open window) if you don't know for certain which you can prove...was the widow open to start, or was it forced open. It allows the prosecutor to offer up two theories of the crime and get the conviction if the evidence at trial supports one and not the other.
If the person is convicted of both counts, the doctrine of merger applies, and the two allied offenses merge into a single charge for which the person is then sentenced. It's not stacking charges, it's kind of the prosecutor's equivilent of carrying a back-up gun.
Your Merry Magistrate...
