100% wrong actually.
hat trick: 3 wickets on consequtive balls from the same bowler, even if separated by innings or match

And sreesanth did take 2 wickets of the last 2 balls in the 1st innings of the 7th ODI vs England.

look at the FOW: 49.5 - LE Plunkett c VR Singh b Sreesanth
49.6-SI Mahmood c VR Singh b Sreesanth
So technically Sreesanth is on a hattrick.
