Indeed a justified question.
I just loaded the general.ctg.
Black's move #6 shows Be7 active only with NORMAL book options. If the book
options are set to OPTIMAL it leaves 6...Nc6 with 94.6% and 6...Bd6 with 5.3%
playing preference.
What is strange is that both with NORMAL and OPTIMAL there is only one active
move for black after 6...Be7 7.O-O: It is 7...Nc6 with 100%.

This leaves some open questions to the SSDF tester I'd say...
