> Ah, so it is because of the multiple apply() calls of an effect?

Exactly. Example:

  <feA result="a" />
  <feB in="a" result="b" />
  <feC in="a" result="c" />
  <feComposite in="b" in2="c">

In this case the apply() of feA was called twice, and the result was generated twice before. This is unnecessary (and usually costly).
