That does seem really weird - just checking I’ve got it right, the downtube cable guides force you to have the rear brake hose cross the rear mech cable twice?
I don't really know as I just got my LBS to do it. I don't think it crosses twice but it does seem to have to cross somewhere. I queried it with them and they had a go at getting it neater but in the end, it had to cross, so... it crosses.
