A man in a centaur suit still has hands so they can carry a package, and if a room has something the size of a very small table in it someone trailing a second set of legs could get there too. Even something the size of a horse could get into most human infrastructure, if most horses weren't so petrified of everything. The man in the article has the equivalent of a big hiking backpack on his back, he couldn't drive most cars either without leaning the seat all the way back. To turn that into a centaur just means angling the same backpack 90 degrees with another set of legs.
