How is cumulative (type) coverage affected by the dynamic creation/destruction of covergroups.

For example:

Given covergroup A:

1. create A1, instance of A with per_instance=0
- at this point, the cumulative/type coverage of A should reflect A1's coverage
2. create A2, instance of A with per_instance=1
- at this point, the cumulative/type coverage of A should reflect A1 and A2 (?)
3. destroy A2
- at this point, how is the cumulative/type coverage of A calculated? does A2 contribute in any way now that it has been destroyed?
4. destroy A1
- at this point, how is the cumulative/type coverage of A calculated? does A1 contribute in any way now that it has been destroyed?
