\ in front a a newline removes the newline before the parser
interprets the code but here, a newline is fine, same as after
||, &&, ;, &, if, then, else, while, do... You can even have
comments:

  set -o pipefail
  print -P - $var | # prompt
                    # expansion

    sed 's/^[[:blank:]]*//' | # trim leading blanks

    wc -c ||

    die "pipeline failed"


At the prompt of an interactive shell, you'll notice that if you
press enter after a pipe, you see:

$ echo foo |
pipe>

Which tells you the parser is still expecting a command after
that |.

Where you might argue it's inconsistent is that you don't get
something similar after redirection operators:

$ echo foo >
zsh: parse error near `\n'

Or after "for"/"select"/"repeat"

$ for
zsh: parse error near `\n'

It's not specific to zsh though.
