There are two things wrong with LH-Front brake cabling, one that it's forrin, and two that it looks ugly on that bike. It actually works better on modern bikes with cables under the tape, because calipers are handed to the more popular forrin method, but it's still wrong.

If you flat on the front in a race, you put your left hand up.
Front brake controls front derailleur and vice versa.
It also makes the cable bend less extreme for the front.
And just looks ugly because you are not used to it.
As much as I hate to disagree with you, LH/Front makes perfect sense, if only I wasn't so used to the opposite!
