Turns out I was wrong... But here were my thoughts before clarification:
For those of you that were on the chat on Sunday I was under the impression that the 20 car illegally passed Robby before the start finish. A little back ground. Prior to the restart after caution #8 Robby stayed on the track. The 20 also stayed on the track but was caught behind other multiple lap down cars. Both the 7 and the 20 were 1 lap down. The other cars let the 20 go in front of them and the 20 was going to line up outside the 7. As the green flag flew the 20 clearly passed the 7 before the start finish to take the 25th position which was the, lucky dog position. Shortly after the 9th caution flew scoring the 20 in the LD spot. Although I did not find the exact ruling I did find and article that addressed a similar situation regarding Carl Edwards in a Nationwide race right after the Shootout restart was initiated:
Then, #2-Kurt Busch's crew chief Pat Tryson wondered about the scenario that occurred in Friday night's Nationwide Series race, when Carl Edwards illegally passed Brian Vickers on the outside before the start/finish line but gave the spot back and was not penalized."I'd stress to you drivers that you're good enough that you shouldn't be getting yourself in that position - stay in line until you cross the start/finish line," Hoots said. Hoots then said that NASCAR officials let drivers figure it out for the first six races, but that they should have the restart procedures down by now. #24- Jeff Gordon to ask Hoots if there was a "grace period" for making mistakes like Edwards did in the Nationwide race. "The grace period is over," Hoots said. "We're serious about it tonight

the 20 finished 21st the 7 finished 24. Given a chance to start in the final double file restart instead at the end of the longest line would have helped the 7 improve. Clearly Nascar missed this one..
