This claim ignores the fact that most computers today are still based on synchronously clocked parallel bus hardware. A common failure mode is clock skew, which causes many bits to be wrong at once. This can even happen within the CPU. As serial interfaces continue to be added to computers, the number of single bit errors (vs multi-bit errors) would tend to increase except for the fact that these serial interfaces are designed to detect and discard erroroneous packets. I do agree that the logic between the self-validating interfaces can be faulty.
