I agree he handled it poorly. What the legislature guy was asking was correct, the black bars on top and sides are used to form a grid to locate the bubbles, and those appear to be correctly aligned.
The problem was some of the bars were about 50% too small. It didn't look obviously wrong but if the scanner is looking for a certain length bar it might consistently fail, which indeed was the problem... Very high failure rates.
Basically I would be asking the same question as that guy, it was kind of annoying.
I think the presenter isn't a very good presenter but what he presented appears to be pretty accurate. A forensic analysis should show up the issues quite well.
