Yeah, she's flexible, but she lacks control. Check out Ashtanga yoga.

Most of those asanas (poses) are held for 15-30 seconds. Also almost all of the asanas from that video are part of the basic set! They are just performed darn near flawlessly. Even the simple jump through from all 4's to the crossed legged position seen in that video several times is exceedingly difficult to master. The levels of balance, strength, and flexibility that advanced yogis posses is incredible.
