That is strange, why do you need to do the \new DrumVoice-lines in 
drummode? Example of 2.5.1.3:

         
         \new DrumStaff <<
           \new DrumVoice = "1" { s1 *2 }
           \new DrumVoice = "2" { s1 *2 }
           \drummode {
             bd4 sn4 bd4 sn4
             <<
               { \repeat unfold 16 hh16 }
               \\
               { bd4 sn4 bd4 sn4 }
             >>
           }
         >>

in "normal" mode they is not needed:

        \version "2.11.52"
        \new Staff
        \relative g' {
          f4 c' f, c'
          <<
            { \repeat unfold 16 e16 }
            \\
            { f,4 c'4 f,4 c'4 }
          >>
        }

This "looks" about the same.

Ok, what happens if you replace the bd4 sn4 etc. with the snares from
last example of 2.5.1.2 ? By doing it this way, a tie is missing:

        \version "2.11.52"
        \new DrumStaff <<
          \new DrumVoice = "1" { s1 *2 }
          \new DrumVoice = "2" { s1 *2 }
          \drummode {
            sn16 sn8 sn16 sn8 sn8:32~ sn8 sn8 sn4:32~ |
            <<
              { \repeat unfold 16 hh16 }
              \\
              { sn4 sn8 sn16 sn16 sn4 r4  }
            >>
          }
        >>
