Ouch! Does it work like this?

If I have elements A and B:
The first time A will match Requirement1 and B will match Requirement2 
and B will be flagged as deleted
The second time B will match Requirement1 and A will match Requirement2 
and A will be flagged as deleted

So will I end up having ZERO requirements?
Or the second time B will not match anything because it was already 
flagged as deleted?

Thank you
Gabriele
