This machine doesn't represent L2 and r2 correctly IMHO.
It also accepts b's, without any a's?
The second paragraph below the FA's has a sentence "It ignores all b's", so FA2 must be the incorrect one.

FA2 of course accepts the null string or words without any a's i.e. 0 a's since 0 is an even number. FA2 is the correct machine for L2 and r2.

In the paragraph description the b's are ignored to explain the way in which an even number of a'a are generated.
