That was my first thought, too (I've certainly modeled enough falls).
But on giving the matter more thought, I note that the shape of this
object is rather wing like. That being the case, especially given its
small size and low weight, I don't see why aerodynamics as it tumbled
couldn't impart a certain degree of horizontal velocity. Consider how a
leaf falls to the ground. This horizontal component would be random and
probably time-variant, with no relation to the original fall direction
(assuming this is a meteorite, which seems doubtful).
