The bands overlap a lot. While the top end for in a product role is likely to be higher, that doesn't mean a guaranteed income change when making the leap. A senior dev will be higher than a junior PM. A very senior (principal level) dev at the top of the compensation band will likely be higher than a first-time PM, even is the role is "Senior". However other commenters are correct: anything in management heads to bigger responsibility and compensation, so the top-end is effective uncapped. It's very different work than writing code though, and it's not for everyone.
