If I may, I think he sees two "plans", one being the insiders plan to slowly and carefully sell off shares because they believe they are on a sinking ship, and another being the plans of daytraders and how they manipulate the price into profitable runs then dump everything and wait for it to plummet again. Wash, rinse, repeat, I think that's how it goes.
Don't stop panicing yet, but you can relax a little.
