It's not the same disc and IMHO it would be wrong to just hack it to compliance, however convenient that may seem in reducing data volume and amount of dumps in DB. Applying additional offset correction apart from what the dumping method already does is totally equivalent to hacking stuff to compliance.
Again IMHO, it's significant to indicate different print runs/different ringcodes, at least when they result in different dumps when using the same standard dumping method.
Also had a similar case with one of my dumps recently that was accepted as separate discs, which of course they are.

I agree with you, but what I want to know is the current rules.
Nope, these aren't the same cases. For the Audio CD we can merge all the tracks into a single image and shift the whole image by 294 samples to get the match, because the entire disc contents is shifted. While for the 1M/2M/3M/etc. ones only some tracks are shifted and even if you leave the data sectors scrambled and try to shift the whole image, it won't match any other one.
In short:
When the whole image is shifted compared to another one => both discs are the same and are only affected by the write offset, should be merged
When only some tracks are shifted compared to another image (all the tracks are shifted, but not the scrambled data track also belongs here) => both discs are mastered differently and shouldn't be merged
