Alternator wiring

Agree that's not how it was originally done.
But it could be routed that way. It doesn't matter as long as its connected well.
The blue dot represents the spliced connection, which could have had a couple more wires but they are not important for your question.

If this is what was done, it will work the same. (as long as the connections are good and the wires not too long)
