I'll try to explain, though no doubt not as well as he can when he is next here.
In the black cable there are several pairs of wire, and the two wires of each pair are twisted round each other. This in some way minimises the interference that gets picked up by the pair - I think it is because they both pick up roughly the same amount and it cancels itself out, or the equipment can do the cancelling because the two interference values are so similar.
A split pair connection is when a wire from one pair is used together with a wire from another pair. Because these two wires aren't twisted round each other they often have different noise levels picked up and so it doesn't get properly cancelled out.
He is saying the blue from the black cable will be paired with a white wire, not an orange wire. So you need to get a bit up where the black sheath is and find the white wire that is twisted round the blue one, and use that instead of the orange one. Then do the same at the other end.
Having said all that, not being an expert and not sure which pic shows wires from where, I don't understand exactly what you need to do, as for example the blue is crimped to a white, where I would have though it sensible for it to have been an ongoing blue.
So perhaps you had better wait for him or someone else who knows more than me, but I hope you understand what he is saying now?
PS - Just googled it and found
this wiki article.
(Edit - just wondering, given other connections there, whether it might make sense to find the white wire that is twisted round the orange and replace the blue with that. The important thing is to get a twisted pair from end to end of all the connections, even if from one socket to another a different pair is used. For instance the pic after the video link has blue with a white stripe, which is I think is CW1308 and would be paired with white with blue markings).
