It's just another conductor in the field of the driven element(s). I
have seen some designs that make the top guy(s) a certain length to be
part of an antenna. This would make guy wire reradiation helpful.
However, without specific planning for placement, lengths of
conducting segments, etc, the ropes-always-snaggle
random-letters-never-make-Shakespear chaos-rules theory of the
universe would dictate that semi- or fully-resonant lengths of guy
conductor in the antenna field will reradiate in ways you don't want.
I don't know whether Lew got lucky or he planned it that way. Maybe he
has a bucket of serendipitous.
