Looking at latex.ltx, you can find:

\ifx\@@input\@undefined\let\@@input\input\fi
[...]
\def\input{\@ifnextchar\bgroup\@iinput\@@input}
\def\@iinput#1{%
   \InputIfFileExists{#1}{}%
   {\filename at parse{#1}%
    \edef\reserved at a{\noexpand\@missingfileerror
      {\filename at area\filename at base}%
      {\ifx\filename at ext\relax tex\else\filename at ext\fi}}%
    \reserved at a}}

This seems to say that, in LaTeX, \input is interpreted:

- If it is followed by \bgroup (= {), as \@iinput which is defined in 
terms of \InputIfFileExists, redefined by pdfsync.sty to support 
synchronization.

- If it isn't followed by \bgroup, as \@@input which is initialized to 
the original TeX primitive \input, untouched by pdfsync.sty and thus 
not supporting synchronization.
