The transformed clone had orders to wait until Obito jumped down or passed into eyeshot and call out to him waving, then see if she could distract him with a little chat. Hopefully long enough for Kushina or one of her other clones to jump into action.

She made a few more and had them hide themselves away as best they could, closer to the training area than herself and the other clones. Those three would gauge Obito's reaction to noticing the disguised clone and one would disperse to pass on the intel to the original Kushina.
