How do swing-path tilt and attack direction describe different geometry?
Swing-path Tilt describes the vertical angle of the bat’s path relative to the ground over the route toward contact. Attack Direction describes the horizontal direction of the bat’s sweet spot at contact, relative to an imaginary line from home plate to straightaway center. They use different axes and reference moments.

Swing-path Tilt is the bat path’s vertical orientation
MLB defines swing path as the shape of the hitter’s swing on the way toward contact. Tilt is the vertical angle formed by the bat path compared with the ground: zero degrees is flat and parallel to the ground; a larger angle is steeper. It describes the path’s vertical plane, not which side of the field the bat is moving toward.
Attack Direction is horizontal movement at the intercept
Attack Direction measures the horizontal direction of the bat’s sweet spot at the contact point, or where bat and ball cross on a swing-and-miss. Its reference is an imaginary line from home plate to straightaway center field. Zero degrees means the barrel is moving toward center; the value is reported as pull or opposite-field direction. For a right-handed hitter, pull is toward left field; for a left-handed hitter, it is toward right field.
One metric describes vertical path orientation; the other describes horizontal direction at the instant the bat meets or crosses the ball. Neither is the batted ball’s spray direction.
A fictional right-handed swing
Hypothetical tracking record: a right-handed hitter’s swing path has a 35-degree vertical tilt relative to the ground. At the contact point, the bat’s horizontal Attack Direction is 8 degrees pull relative to the home-to-center reference, toward left field for this hitter. The values are invented; 35 degrees describes vertical path shape and 8 degrees describes horizontal movement at contact. They do not state where the ball landed.

Does an 8-degree pull Attack Direction mean the ball was hit to left field?
No. Attack Direction describes the bat’s horizontal movement at contact relative to the home-to-center reference. It is not the batted ball’s direction after contact.
