No. She raised the turn because she thought her hand might be best and to charge a draw where she could take a free showdown. She knows IF BK called her turn raise there is no value in betting the river unless she imrpoves because either BK is on a draw and will not call or has a made hand better than her hand and will call her river bet. She uses her positional edge to extract the max and lose the min against a passive player. It also has the added benefit of potentially folding some better hands, like 99 ot TT or a weak J.

By BK willing to 3 bet the turn it helps negate some of her positional edge as she will be less inclined to use this move against him and play more straight forward against him in the future because now she will be more inclined to get to showdown. Plus she doesnt get to she his cards which has added benefits (until he tells her).

An important note in all of this is that BK needs to realize that her future turn raises against him will probably have more strength as she now must fear a turn 3 bet from him and she will be less willing to do this with marginal hands.
