Not asserting I'm right or wrong, just my observation here: in your picture the girl in pink does appear to be in front the girl to her left in black (our right) but I re-watched the White House official video and at 7:53 it looks like the girl in pink is behind.
edit: Ok this is a truncated video that isolates the discrepancies. Keep watching til the end when it goes to a wider angle, the girl in pink is gone. She definitely walked up to the platform along with Joe, Jill, and the other girl.
