Yes! :-)  Exactly so.

And the motivation is: I wanted to have it sound a bit like
Plattdeutsch of the region I originally come from.  It is quite rich
of diphthongs and I like them a lot.  Especially /uI/, /iU/ and /Eo/.
I'm not too fond of /OI/,/OY/ (or maybe /oI/), so it shifted to /uI/
in S9.

(There is also a dialect with the triphthong [y26] in |krn| /ky26n/
'to talk'. My grandma's dialect uses two syllables: |kuiern| ['kuIj6n])
