The inhauls are used to put your jib into extreme "pointing mode". So you tighten them only when going upwind. Therefore, you can expect that you will want to adjust them when sitting on the "high" side.
On my boat, simply let the lines cross each other. There's no separation between fairlead and cleat. (Because the lines are so lightly loaded, I didn't even have to attempt to orient the cleat/fairlead in any way; the 90 degree bend as the line enters the cleat simply doesn't matter for this application).
I've sailed with someone who never sat on the rail (and certainly never hiked). In his case, crossing the lines did not make sense, because that put the tail too close to where he liked to sit. (He also liked to face backwards a bit). His boat was a DS2 which has a small "lip" at the edge of the cuddy. That meant, we could mount the cleats on the top and let the tails lie on the cuddy top. On my DS1, they would fall down anyway, and I like the way the cleats are lining up on the edge of the cuddy.
The moral is, just place the tails where you can adjust them when seated for going upwind. You may not need to "play" these constantly, but they do want to be adjusted based on wind conditions, and in variable winds you'd expect to adjust them a bit.
You also would release them when not going upwind. That means that sometimes you need to release them after you've started going downwind because you forgot to do that in time. So, don't mount them where you can only reach them while hiking
Mine ended up in a compromise position. I can get to them from the upwind side, but not when full-out hiking (something that seems rare, anyway in the prevailing conditions). I would need to lean in, just a bit, but that's not been a problem. At the same time, they are not so far outboard that I can't reach them when sitting inside on the leeward side for a downwind run and need to release them.
