Yes, 560uH is the nominal value used in the test circuit (which is just the circuit they use to specify the "typical" values in the spec. sheet).
However, if you look at the application notes (AN-H33 & -H34), you'll see a range of inductor values used in different circuits. The "PDA"-type application circuit shows a 220uH L1 used.
I could measure the value of mine; it was too damaged when it broke off. But someone else did, and reported that it was 220uH. So that's what I used.
