You're right, and that's what the canvassing process is there for, and it would catch something like this being used.
In the specific case of Detroit (Wayne County), there was a discrepancy of 433 votes spread out over 179 precincts. That is MUCH more likely explained by sporadic cases of people not signing in correctly, joining the wrong line, entry errors, etc. It's not feasible that this kind of tech vulnerability could be used on that many separate machines in such small numbers to have some kind of real effect.
