I have a hunch the T.O. Power in this context really means TLs in FLEX/MCT or TOGA detents. But you are right it does not spell that way, something I underscored above and thus could be wrong.
Regardless, it is would be hard to test. The G/A drïll has some steps:
1) TOGA selection
2) ..
3) ..
4) ..
5) ..
6) ..
7) ..
8) ..
9) ..
10)..
11) L/G downlocks release
The T.O. Power will be well before 11) happens.
Challenge to fill the blanks offered.
