The poster points to the fact that typically you have Jira tickets to write the code, and that’s assigned to you, and that adds to your velocity, but the reviewer of the code doesn’t get any credit for spending time on this. Thus in teams where the program manager doesn’t try to account for code review and they actually try to incentivize velocity (both stupid), you’re not incentivized to do thorough code reviews.

I think you've read that the wrong way round.
