Effects of changing a node in a binary tree

Question

Suppose I want to change orange nodein the next tree.

So, the only other change I will need to make is this left pointer green node.

blue node will remain the same.

Am I mistaken somewhere? Because according to this article (which explains lightning ), even the blue node needs to be changed.

Similarly, in this picture (repainted) of the same article , why do we change the orange nodes (when we change the node x)?
