You don't have control structures in TypoScript, just one huge array of
properties. "if" is no control construct, its just another property of
the stdWrap function (for the TEXT object, in this case).

So this "if" applies to the TEXT element.

  if.isTrue.data = page:author_email
  dataWrap = <A href="mailto:{page:author_email}">{page:author}</A>
  if >

is the same as

  if.isTrue.data = page:author_email
  if >
  dataWrap = <A href="mailto:{page:author_email}">{page:author}</A>

because order doesn't matter on those named properties. You see that
your "if" is deleted and never applies. Most "if/else" constructs can be
emulated by a COA with two elements:

lib.author = COA
lib.author {
  # Case when there is no Email
  10 = TEXT
  10.data = page:author
  10.if.isFalse.data = page:author_email

  # Case when there is an Email
  20 = TEXT
  20.if.isTrue.data = page:author_email
  20.data = page:author
  20.dataWrap = <a href="mailto:{page:author_email}">|</a>
}

and there might be other ways to do that in TS.
