In part, I think the \tag being named #'here is adding to the confusion.

A \tag is not a location per se, but rather it marks the following bit 
of music with some identifier.  It is then this marked music that may be 
modified by subsequent commands.  Consider:

%%%%
\version "2.19.83"

someMusic = \fixed c' {
  %%        pushTo --.     .-- appendTo
  %%                 v     v
  c4 d \tag #'first { e f g } a \tag #'second < b d' > c' d'
  %%                                           ^    ^
  %%                                  pushTo --'    '-- appendTo
}

{
  \cadenzaOn
  \appendToTag #'second \tweak style #'harmonic f''4-2 %% Last
  \appendToTag #'second \tweak style #'cross f''4-1    %%  ^
  \pushToTag #'second \tweak style #'harmonic g'4-2    %%  |  Order
  \pushToTag #'second \tweak style #'cross g'4-1       %%  |    of
  \appendToTag #'first \tweak style #'harmonic g'4-2   %%  |  Appli-
  \appendToTag #'first \tweak style #'cross g'4-1      %%  |  cation
  \pushToTag #'first \tweak style #'harmonic e'4-2     %%  '
  \pushToTag #'first \tweak style #'cross e'4-1        %% First
  \someMusic
}
%%%%

Hopefully my crude ASCII-art above makes it through intact.
