Crossover wiring

I have read through Gartner's Wiring for DCC website and I might just have brain freeze but I feel it best to ask the question before I really screw something up.

I have 2 parallel tracks wired correctly for DCC (NCE PowerPro). Looking down east along the tracks, the left hand rail of each track is wired to the same side of the DCC bus (black wire) and the right hand rails are similarly wired to
the other side of the DCC bus (red wire). I am going to construct a cross over between the 2 tracks so a train say going east on track A can cross over and run east on Track B. My turnouts will be 2 Walthers code 83 DCC friendly turnouts.
On these turnouts the frogs are isolated with cuts in the frog rails fore and aft of the frog, and internally the turnouts have jumpers to power the rails.

As I look at these turnouts, I will not have to insulate the diverging routes of the 2 turnouts from each other where they meet but can just solder the rail joiners between them. The plus and minus rails through the crossover are consistent and do not electrically touch each other except at the frogs which are isolated and non-powered (The frogs, of course could be power routed through the tortoise contacts.) Am I correct in my assumptions here?

Now this morning I connected the 2 diverging routes of the turnouts as a crossover, ran continuity tests with my multimeter which proved OK and no shorts and then made a temporary DCC connection from my NCE PowerCab bench test unit to the point end of one of the turnouts. I successfully ran a sound locomotive back and forth through the crossover. Maybe I am confusing DC wiring with DCC wiring, but since the turnouts both are DCC friendly with isolated frogs I should not have any shorts. Right?
