Firstly, I'm not certain there is basis for this claim. Most human
counting problems are caused by a lack of clarity on the original
record, be it pencil-marks or chads. Since any useful voter-verified
audit-trail is likely to consist of simple clearly-printed preferences,
which have been verified by a voter before being cast, there is every
reason to believe that accurate counting with good transparent human
counting procedures are implementable. 

Secondly, how does one determine if the system has or has not worked
without checking the audit trail? If the electronic result says
candidate A beat candidate B, how do you know if that is accurate without
performing a comparison?  

Since this comparison is the key to any successful integrity check, it 
seems that we still need a transparent, human-auditable counting system
anyway - to verify the veracity of any electronic results.

There is, as yet, no credible mechanism by which an auditor can decide
- merely on the numbers - whether an electronic result is likely to be
erroneous or not. Opinion and exit polls are frequently wrong, and an
electronic system may be as likely to mis-count one vote as a thousand.
What mechanism can be proposed?

Electronic systems are not open to non-destructive or unassisted review, 
their implementation is sub-microscopic.
