Again - the 'cut' relates to way you *intend* to use
the crystal - if 'cut' for parallel use and used in
a serial resonant circuit the freq will be off ...

The oscillator circuit the crystal is used in determines
whether the 'series mode' or 'parallel mode' of the crystral
is made use of - they are *still* both present as far as
the crystal is concerned - but it's the osc circuit that
makes use of one or the other.
