That's bollocks I'm afraid. The flights are only useful if they are booked in classes which are eligible for AA points/miles. Unfortunately, OW RTW tickets in Economy are booked in L, which isn't eligible on many of the airlines.
Details of eligible classes for each of the airlines are here:

Your point that you can get a challenge without flying on AA metal is valid though.
