I'd check what they were connected to rather than just reversing them and doing a smoke test.
this IS correct.
not to get too deep into it but the reason is the signal out of the dist is "upside down" for what the MD needs. its like connecting a MM to a battery. one way you read 12v and if you flip the lead you read -12v.

it wont hurt anything if you flip the leads back. If it WAS correct the car will not start. if it was NOT correct the car should start but will rev to around 2k RPM or so. the reason is the timing will be extremely advanced.
I found this all out when I put an MSD in my 930.

the wires running together will not hurt. the voltage is pretty low on the 2 wires.
