Why did Deepika nominate Shree but saved Surbhi?

Just saw the Monday and Tuesday episodes. BB tells Deepika and Deepak that if they don't make a decision they both will get nominated. At that point Deepika gives in and nominates Shree.

But for Surbhi she tells Romil she is willing to get nominated if no decision is made.

Also, she gave her seat to Surbhi instead of Shree. Why?

Confused

Because Sree n Dipika don't have any plan. They just play to make their least favourites lose. In all the captaincy tasks they supported someone only because they hated the other contestant and NOT because they liked whom they supported. Whenever they tried to play a task their main intention would be to bring down Deepak, or Romil or Kv or Rohit. I have noticed this always.

Deepika already had a half cross on her photo while Deepak had none when the situation of choosing between Sree and KV arose. BB told them that if they could not reach a decision by Aapsi Sehmati then both of them with get half cross. Getting another half cross meant a full cross for Deepika getting her out of the race whereas it meant only half cross for Deepak keeping his contendership alive. So Deepak had an upper-hand in this situation.

But Shree was in the same situation with one cross already and one on Dipika but he chose Dipika!

The second situation was when she had to decide along with Romil between KV and Surbhi and both she and Romil already had half the cross making them even position in decision making. So if Romil refused aapsi sehmati he would also get a full cross along with Deepika getting them both out of race. So Deepika knew he would give in to her demands.
