TPS54611 Stability for 2.2uH Inductor Graph

Other Parts Discussed in Thread: TPS54616, TPS54611

I got the design circuit below for TPS54611 voltage regulator from the TI tool SwitcherPro; Vin = 5V, Vout = 0.9V, Iout = 4A. The tool show L1 = 2.2uH and C2  = 270uF. But, according to Figure 3 on the TI application note SLVA105A, "Designing With the TPS54611 Through TPS54616 Synchronous Buck Regulators", the capacitor value of 270uF is outside of the regions of stability for 2.2uH inductor. Question: Which information is correct, the SwitcherPro circuit or the application note graph?

Graph from the TI Application Note is below.
