Yes, this is a case of the documentation being wrong; it was recently
corrected. Rule 10 now says:
10. _Forced joining_
If the `(j)' flag is present, or no `(j)' flag is present but the
string is to be split as given by rule 11., and joining did not
take place at step 5., any words in the value are joined together
using the given string or the first character of $IFS if none.
Note that the `(F)' flag implicitly supplies a string for joining
in this manner.
11. _Simple word splitting_
If one of the `(s)' or `(f)' flags are present, or the `='
specifier was present (e.g. ${=VAR}), the word is split on
occurrences of the specified string, or (for = with neither of the
two flags present) any of the characters in $IFS.
If no `(s)', `(f)' or `=' was given, but the word is not quoted
and the option SH_WORD_SPLIT is set, the word is split on
occurrences of any of the characters in $IFS. Note this step, too,
takes place at all levels of a nested substitution.
Note that the reference to rule 17 [the (z) flag] has been removed from
rule 10 (and rule 11 is new).
