Okay, thanks. That makes a bit of sense.
I think it would work like:
Kostner is top 10 at Worlds. No other Italian girl entered. Italy qualified for 2 spots on the previous method
With the new one, 1 spot would be qualified. Italy would send a girl to Nebelhorn. If said girl, whoever she is, finishes in top 6 at Nebelhorn, Italy confirms the second spot. Then Italy can send to Olympics Leccardi even if it was Russo who skated at Nebelhorn.
