I don't think it is possible, although I might be wrong.
Because the way I see it, for loop A be interfered with another loop B, while POT, there must be at least one block that belongs to loop A that is dependent on at least one block in loop B. But then loop B must be finished before loop A, and actually inside it. Otherwise, it won't be recognized as a separate loop.

I hope I explained it clear enough. Otherwise, can you please give an example?
