I just took a quick run through the standard, and basically you're correct. The only sections that involve verification and that apply to Class A are:
5.1.6 Software verification planning
8.2.3 Verify changes
9.7 Verify software problem resolution
I don't think it's puzzling that FDA's requirements don't mesh exactly with this ISO standard, since the classification categories are slightly different, the two sets of requirements were developed mostly independently, and FDA has a different approach than the EU, MDD, and ISO.
