It's distance issue. The one on the right has more reach than the one on the left.
3-7 stance -> 4-6 stance -> horse stance - bow-arrow stance with bend back leg -> bow-arrow stance with straight back leg -> monkey stance -> golden rooster stance.
When you throw a punch at your opponent with bow-arrow stance, if you straight your back leg, you will get that exter 1-3 inches reach than if you keep your back leg bend. Sometime you do need that extra 1-3 inches to be able to land your punch on your opponent's body.
If you can make your back arm, chest, fore arm into a straight line with bow-arrow stance with straight back leg, you can have the maximum body stretching and maximum reach. That's the long fist principle. Since Taiji came from long fist, this principle also apply on Taiji too
