You'd have to go back a couple of pages, but here is an example of what I'm trying to say.
You are descending to an altitude in HOLD at idle. You are cleared a visual approach and, for arguments sake, inadvertantly set 0' on the MCP or wind it to a higher MAA.
You turn off your F/D but the PM forgets to cycle his so it remains on. You are a little hot and high and assume that the autothrottles are attempting to control speed in idle as you aim to be stable at 500'. Like they have done in every approach you've flown to date. You don't notice the FMA is still HOLD and assume it changed to SPD when you turned your F/D off.
When you lift the nose to intercept the glidepath from above speed decays rapidly ....
I have never seen this scenario happen; I'm surmising from the FCOM.
I'd be happy to be corrected.
