Yes, correct. That's what we have been saying in numerous posts.
Is doesn't matter if you think the position is past the meridian, or if SGP thinks the position is past the meridian, it's what the mount thinks that matters. If the mount doesn't think it needs to do a flip then it won't.
The reason for all the syncing is that there is disagreement about the mount position relative to the sky and given that there must be uncertainty about when the flip will happen. Once you start syncing, especially offset sync, you don't know where the mount thinks it is pointing and so when it will expect to do the flip.
In addition it may be possible that an advanced mount such as a Paramount can be set to have the flip position set differently to the meridian. Even the Celestron mounts can be set so the flip happens up to 20 degrees before or after the meridian.
This is why I'm suggesting that SGP should have some sort of retry when a flip fails. This would allow the sequence to continue with no consequences other than a delay.
