Joe Did you look a the drawing slownsteady posted on one of his threads. It clearly shows the hot and the neutral in the same cable. They use the lighting box to do there make up. There is nothing in the drawing he posted that was a code infraction as long as it is done in romex and not single conductors. The way it looks it was probable done done as part of remodel. It is not they way i would wire it but i could not find anything in the nec that prohibit it from being done this way.

Reason: do not have time to finish at the time i posted
The drawing I see shows the fixture neutral going to 'other neutrals', not back to the switch box and with the travelers back to the source. It wouldn't be the first time someone picked up neutrals from another box and that is wrong.
