Yeh, they're the same as re070s - you end up with the tread pointing in opposite directions, but the only thing you have to take into consideration is that they have a definite "outside." And they're labeled as such.
I thought it was a little odd at first, too. I imagined that since the tread was supposedly "designed" for water evacuation, having the tread going the opposite direction on one side would just screw it all up. But having driven in heavy rain on my RT615s, I can finally say that the tread doesn't matter - wet traction blows no matter what.
