(One could question the correspondence even for Chinese.)

The "syllable" wording might have been chosen in reference to rules
concerning punctuation and ruby annotations and the like.

I see that the current text requests references for line breaking;
http://en.wikipedia.org/wiki/Line_breaking_rules_in_East_Asian_language
has some references, including references for Korean.  Some of the
pages that it references (including the corresponding Japanese and
Korean wikipedia pages on which the English page was based) may have
additional information.
