That is not true. If the Cowboys lose and the Hawks win, the Vikings, Packers and Seahawks will probably go b/c of this 4th tiebreaker called "strength of victory" that takes the average winning percentage of all teams you beat (kind of like the BCS). As of now, the Seahawks strength of victory is higher than the Cowboys, so unless that changes this weekend, the Seahawks might not need GB or Minnesota to lose, only the Cowgirls.
