Why does SoftDelete uses cloned model?

[wurst-hans]

Why does SoftDelete behavior work with a clone of original model?
What could happen if we just call save() on the original model?

[Jeckerson]

Could you please specify your concerns about it? With some basic examples...

I have no concerns. I just want to understand why this is done. In source code there is a comment, that save() is done on a clone of model to ensure a clean operation.
Has this been done, because you fear any interferences when calling save() on the original model while delete() is running currently on it? The only thing I can imagine is, that the skipOperation() called on original model might have side effect when executing save() on model instead of clone. But I have no clue.
