Lukas and Kieren are talking about different input methods
for the same thing. Your first example is equivalent to

{
  \voiceOne
  c''4\< 4 4 4
  4\> 4 4 4 <>\!
}

i.e., the hairpins conceptually extend over the bar lines, and
graphically stop over the bar lines because Hairpin has
to-barline = #t by default. This is completely different
from your second example. The latter expressed with empty
chords would be more like



<<
  {
    c''4 4 4 4
    4 4 4 4
  }
  \\
  {
    <>\< s2.. <>\! s8
    <>\< s2.. <>\! s8
  }
>>
