The way I understand though, you only need two for each tank...the main t-stat (which is plugged into the backup) controls the temperature normally, but then if gets too hot, the backup will cut the power to the main. If it gets too cool then, the backup will allow power again, and the main will run at full power. (the backup should be an on/off, not a proportional)
However, it is true that if either of your stats fails in the off position, then you won't get any heat at all.
Of course, you could use 4 if you are controlling two different heat sources with two different t-stats each.
