It doesn't matter, she obviously changes all manner of direction, orientation, or speed of anything she teleports. We'll just stop viewing it in terms of real-world physics and the assumption she only changes location, and back to Esper's broken physics.
Looking at just her fight with Sherry, Kuroko changes quite a few things. Her Teleport Judo Throw switched the orientation of Sherry from vertical to horizontal without Kuroko moving at all. Furthermore, she fell parallel to the ground after Mikoto fired the railgun destroying the arm of the golem. Kuroko teleported back to vertical position, but instead of moving the same direction and speed (her back falling "down"), Kuroko landed with a much lighter landing hop (feet falling "down" at a much lower speed). She also had enough time in the limbo stuff goes through to extend her legs out again (compare 20:03 to 20:06).
The needles were sent sequentially, so she changed their layout from a tight circle around her leg to the precise pattern to pin Sherry. She obviously can control the orientation, vector and corresponding magnitude of anything she sends. Otherwise, when she shifted herself, she would hit a surface as fast as she was moving before.
There.
EDIT:
Either that or she's being deceptive about the extent of her abilities. She's not just a teleporter, she's got psychokinesis too.
