After much review and discussion, the scientific community said that this strike is something known as a secondary lightning strike.

HowStuffWorks explained that there is a phenomenon of secondary lightning strikes. “It is very possible that a main strike can be followed by 30 or 40 secondary strikes. Depending on the time delay between strikes, we may see what looks like one long-duration main strike, or a main strike followed by other flashes along the path of the main strike.”
