What do do on spent flowers of this Epidendrum

[jai_star]

The current book i'm reading states that " It is not necessary to remove the flowered tip of exhanusted flower spikes as these frequently produce secondary flowerings spurs rather than shoots which grow from the medium or lower of these stems" - (Expanding your orchind collection, J.N.Rentoul )

So I'm confused once the flowers fade and drop off I don't cut the stalk but where will the flowers come from againg? The apex?? Anyone here can explain ?
