    I suggest that any leftovers (boosters, etc.) would not go in orbit. 
    The spaceref article 
    ( said that the 
    target was 4 degrees west (about 390km overland at that latitude) and 
    its altitude about 865km. The angle of attack would be something 
    around 66deg - pretty steep for objects to enter orbit. I strongly 
    doubt it went straight up, turned sideways near 800km and reached 
    orbital speed.
    An interesting problem though:
    According to , range 
    safety concerns constrain the launch azimuth to between 94 and 104 
    degrees or approximately EAST. How did they shoot something to the
