 Nominations are not supposed to be written in alphabetical orders. When a housemate nominates two names the appear as
1st Nomination,
2nd Nomination.
Only when the nominees are resulted, they are specified in alphabetical order. If you watch the show closely you will see that the pairs were nominated as ""We want to nominate Sampat and Sana"". Therefore Sampat's name has been introduced first and then Sana's in the table.  chat  "
