Anyone can explain the Examples 1 in 1671E to me?

Revision en1, by thedesalizes, 2022-06-15 12:33:26

Why the answer is 16 but not 8 in Example 1? I can only figure out the 8 strings below

B AAAAAAA ABBABAB B AAAAAAA ABBABBA B AAAAAAA ABABBAB B AAAAAAA ABABBBA B ABBABAB AAAAAAA B ABBABBA AAAAAAA B ABBABBA AAAAAAA B ABABBBA AAAAAAA
