That's strictly speaking to true:  NTP *assumes* symmetric delays.

If your path is not symmetric, you can a time offset of half the asymmetry.

If your path is stable you can calibrate that out with a temporary reference
or something.

If you path is not stable, or you flip between different servers with different
delays and/or assymetries, your time will not be stable.

Never attribute to malice what can adequately be explained by incompetence.
