String pattern one piece and two piece?

[LuxilonTimo]

I was looking at racquets and was wondering what does one piece and two piece mean on the string patterns category. Here is some examples.

String Pattern:
16 Mains / 18 Crosses
Mains skip: 7T,9T,7H,9H
One Piece
No shared holes


String Pattern:
16 Mains / 20 Crosses
Mains skip: 7T,9T,7H,9H
Two Piece
No shared holes

with two piece stringing you use 2 separate lengths of string for the mains and crosses

you can string two piece anything since you can widen the holes anyways.
