Section 5.1 says:

The plain text to be encrypted is split into 64-bit blocks. Input of a binary data block Tp = (a1(0), a2(0), ... , a31(0), a32(0), b1(0), b2(0), ..., b32(0)) into the registers N1 and N2 is done so that the value of a1(0) is put into the first bit of N1, the value of a2(0) is put into the second bit of N1, etc., and the value of a32(0) is put into the 32nd bit of N1. The value of b1(0) is put into the first bit of N2, the value of b2(0) is put into the 2nd bit of N2, etc., and the value of b32(0) is input into the 32nd bit of N2.

It should say:

The plain text to be encrypted is split into 64-bit blocks. Input of any binary data block Tp = (a1(0), a2(0), ... , a31(0), a32(0), b1(0), b2(0), ..., b32(0)) into the registers N1 and N2 is done so that the value of a1(0) is put into the first bit of N1, the value of a2(0) is put into the second bit of N1, etc., and the value of a32(0) is put into the 32nd bit of N1. The value of b1(0) is put into the first bit of N2, the value of b2(0) is put into the 2nd bit of N2, etc., and the value of b32(0) is input into the 32nd bit of N2.
