It seems right to me. If the chance of one ticket winning is one in 10^6, the chance of four specified tickets winning four drawings is one in 10^24.
Of course, the chances of “Person X winning the lottery week 1 AND Person Y winning the lottery week 2 AND Person Z winning the lottery week 3 AND Person W winning the lottery week 4” are also 10^24, and this happens every four weeks.
