Which makes sense. If the salary cap is expected to rise, tomorrow's dollars are cheaper than today's dollars. Pushing contracts into the future lets a team get more for their dollars now. Then that value gets more team friendly during future seasons.
Where the Saints got stung is COVID causing the cap to stagnate. I believe Loomis had all the contracts planned out into the future expecting a certain cap expansion. When it didn't expand anywhere near the expectation, a lot of the Saints calculated moves became very troublesome.
