No, it is totally unrelated.

Your issue is explained in the NEWS for Emacs 22, and in the documentation
of the variable sentence-end:

  The value nil means to use the default value defined by the
  function `sentence-end'.  You should always use this function
  to obtain the value of this variable.

So auto-capitalize should use sentence-end the function, not the variable.
