You're missing the shape of the brackets in "<variable
id="$ALetter">($ALetter $FEZ*)</variable>".  The brackets are round,
not square, so <U+0308> does not match $ALetter as it is not a string
starting with something for which Word_Break=ALetter.  Obviously
<U+0001, U+0308> does not match either.

Secondly, if you read
http://unicode.org/reports/tr35/tr35-general.html#Segmentations, you
will see that the final rule of "Any ÷ Any" is implicit.
