I stand instructed.

So, let me see if I got this straight:

The causative suffix *-ejo-/*-eje- assumes the special
form *-jo-/*-i:-, of which the first has an initial -j-,
the second doesn't, which combine with a preceding -s-,
here from -k^-, to form -s^- and -s-, respectively
which immediately refutes my suggestion.

Does this happen also after a stem in final PIE -s-?
