Is so seldom that I see legitimate, helpful and correct advice on this site, i had to comment.
You're 100% correct. There's no way to properly fix the cracks, without first grinding and providing a proper base for flexible sealant. I left that part out of my post, because that's the pain in the butt part of the job, that hardly anyone does.
