That pretty much restates my original question in a more concise way. So far, we've got peole saying it behaves the same as the autoland and people saying it stays in SPD until anywhere from 25' RA to a few seconds after touchdown, then the autothrottle FMA goes blank -- no IDLE. CCA said he even got the AUTOTHROTTLE caution when it went from SPD to blank after touchdown. It is appalling that Boeing doesn't explain this better.
