Generally speaking, we would not have any reason to doubt this. Have you observed anything that would suggest otherwise? We would also suggest that all of COM pins be tied to a common point on the PCB, just out of "best engineering practices," if for no other reason.
Thank you! It might help to share more details on what you are observing. Perhaps some data or a plot of the unexpected behavior might be helpful. Is this on one unit only? Are other units, which have all of the pins grounded, behaving the way that you would expect?
All the COM pins of ADXL32x have to be connected to the same GND. If not, part of the internal circuit will be floating or say will cause the unfixed level, then the output will be unfixed too.
