What is it?
position
We say a design has position when placing it in one sense or another yields a distinct, and perhaps unintended, effect, breaking the continuity of the design. And we say a design lacks position when placing it in one sense or another maintains the continuity.
When it comes to a rectangular tile like the example below, it can be placed in 2 positions with respect to another. One would be the normal position and the other by rotating it 180º. (This particular design has continuity and also has position)

Initial position

Rotated 180°
If several tiles are placed side by side without considering the position, the undesired result could be this:

Tiles that do not respect continuity
Do we notice the difference in the tile continuity from the leftmost tile compared to the rest?
When what is really sought is to take into account the position in which they are placed, obtaining the following result:

Tiles respecting continuity
The same happens if we keep placing more pieces.
If the position of the tiles in the next row is not taken into account, a kind of cut is noticeable in the union between the first and second rows:

6 pieces without respecting continuity or position
6 tiles placed in the same position break the continuity between rows.
However, if we take into account the position rotating 180º the 3 pieces from the other row maintain the desired effect (in this case of undulation):

6 pieces respecting continuity and position
We hope these examples help clarify both concepts.
