LOL, if I knew more I wouldn't be asking <g>.
I am not a real-world pilot.
But please clarify:
Are you saying that the APP MCP light will be ON from the instant I press the APP button, and that the HDG MCP light extinguishes at the same time?
If that is the case, I assume that despite the non-lit HDG light, I am still in HDG mode, in conmformity to my PFD mode annunciators, and I can still change my heading via the Heading knob until the A/P starts intercepting the LOC, despite the fact that the HDG light is turned OFF, right?
Also, can you please clarify what you mean when you write:
"then APP becomes selected and may be de-selected until GS intercept, so only after intercept does it become impossible to de-select"
If I want to de-select APP mode after GS intercept, for whatever reason, and there can be many, do I have to turn the A/P OFF? There is no way I can de-select the APP mode?
