Dynamic Group Applies to scripting

The reason you can't do it is that the dynamic group membership may bring the resource into the group, which potentially causes new properties to be inherited, which may disqualify it for membership, ejecting it from the group. Upon ejection from the group, the inherited properties reset and the device qualifies to be a member again. This causes an infinite loop. There could and should be something built into the product that prevents that loop from causing issues, but it hasn't been built yet.
