Correct. The first action (flight directors off) ensures the autothrottle either remains in, or switches to SPD (very easy to demonstrate this from e.g. HOLD / (roll mode) / FLCH SPD).
The second action (PM flight director on) ensures continued go-around guidance as has been stated.
It’s in the circling approach (and maybe other) sections of the FCTM.
