'Kitti dataset Pi matrix. Pi is the same with Pi_rect?

Do i understand right that Pi in KITTI calib.txt files is the same with Pi_rect in their paper?: Pi_rect from paper

But what i can't understand it why last column in projection matrix in the paper doesn't equal to the column in real calib.txt files (P3 for example):

7.215377000000e+02 0.000000000000e+00 6.095593000000e+02 -3.395242000000e+02 
0.000000000000e+00 7.215377000000e+02 1.728540000000e+02 2.199936000000e+00
0.000000000000e+00 0.000000000000e+00 1.000000000000e+00 2.729905000000e-03
