repeated neighbours

[gabriele]

From Indian Championship.

The cells having repeated neighbors (cells sharing an edge) are marked. Cells
which are not marked cannot contain repeated neighbors.

Please, may you explain better to me the rules which manage this variant?
I don't understand exactly the meaning of "repeated neighbours": if a yellow cell contain the number 3 with 2 and 7 before and after and 5 and 8 up and down in this way:
* 5 *
2 3 7
* 8 *
it means that another 3 in another yellow cell has the same four numbers (2, 5, 7, 8) near and in the same position?
Thank you very much.
Joe.

no Joe alias beppe

a cell X is yellow when
* A *
B X C
* D *
at least one of the following is true
A=B
A=C
B=D
C=D
you can also have
A=B and C=D
or
A=C and B=D

this is yellow

Thank you very much, Gabriele.
So if I've understood well, the rule is simply:
a yellow cell cannot have in the four near cells (right, left, up, down) four DIFFERENT numbers. It's necessary that two (or more if possible) of these four near numbers are the same number. Ok?
Thanks, Bye bye.
