It's like bowls, or curling (the sports). It's a million mile curl. At the end of the curl, the telescope has close to zero radial velocity with respect to Earth (that is, its orbit around the Sun is parallel to Earth's and has the same period). At that point there will be an orbit injection burn to put it into a small elliptical orbit around the Lagrange point.
