It's not a requirement for removal. The pattern is devised so that the gasket is compressed evenly during the installation. By starting in the middle and working outwards the materials will settle in evenly. If you were to randomly tighten the bolts it's possible that the gasket could create a small "wrinkle" where two areas of pressure converge and possibly leak or cause a failure point. However during removal that isn't really an issue.
