Greg Shaheen answers your geography question

Greg Shaheen played a major role in running the NCAA Tournament for 12 years before leaving the NCAA. He is on Twitter and apparently took many questions from people who, like myself, found it odd that top-seeded Wichita State could potentially be placed at a geographic disadvantage (primarily by playing games closer to Kentucky than Kansas) against lower-seeded teams.

Shaheen, on Twitter, explains that the committee only geographically protects the top seed in its first game.
