| * Expands to the positional parameters, starting from one,

| splitting will be performed, any empty fields may be discarded
| and each of the non-empty fields shall be further split as
| described in Section 2.6.5.

| By the very meaning of this the fields are split individually, *first*
In effect perhaps, but POSIX never specifies the implementation
details. As long as the implementation produces something within
what POSIX expects, how that happens is irrelevant.

That's fine, and, here at least, the only person worried about
what you're doing potentially being wrong, is you.
If you want to match bash exactly, then that's what you need to
do, regardless of whether bash is correct or not. If complying
with POSIX is the aim (pretending you're a shell for a minute) then
there is a bunch of latitude in this area. Note, there is (and was)
no claim that the mksh results I showed in an earlier message were
incorrect, those are within spec too - just different (other shells
do the same, mostly ksh variants, but also yash).
