Hmm... it looks like mail... mmmh, it tastes like mail... it _is_ mail!
Once upon a time (Tuesday, May 6, 1997 to be precise), Barry Block wrote a

By using the stack you are accessing the memory at location SS:SP. This is
not good if SS and SP are corrupted and may point to e.g. the interrupt
vector.

The same result, yes, but you might cause some damage in the process. You
would even hang the system if SP=1.

If the stack is the same, what's the point in saving SS and IP?
