An odd parallel

"¤%&%&"%!!! My OCR program has crashed. I can't access and check my
copied library.

Therefore this is by memory and correct me if I'm wrong: In several
IE languages, Tocharian among them, a new present has been formed by
a suffix, one of which is *-sk-, leaving the old present in its
former "peripheral" role as subjunctive, future etc.

Now watch this:
"
[In Proto-Permian the] future tense was morphologically distinct only
in the third person; this is still the cas in present-day Zyrian
[Komi]:
munë "(s)he goes", munënï "they go"
munas "(s)he wil go", munasnï "they will go"
Otherwise, present and future forms syncretized [TP: or were
identical?]
Zyrian [Komi] has retained the old pPN [proto-Permian] tense
system. ... the future is restricted to the third person...
In Votyak [Udmurt], on the other hand, the tense system has undergone
restructuring. Once again a frequentative suffix is to blame: the
derivational suffix =s´k came to function as a present-tense marker.
This morpheme now occurs in the first and second persons of the
present-tense paradigm, eg.
mis´k-is´k-o "I am washing"
das´a-s´k-odï "you (plur) are preparing"
The future tense, originally formally distinct only in the third
person, now came to differ from the present tense in all persons, ie.
alongside the original distinction between
mis´k-e "(s)he washes" and
mis´k-oz "(s)he will wash"
there arose the new and parallel distinction between
mis´k-is´k-o "I am washing" and
mis´k-o "I shall wash".

What the !#%&/%?

Why does one of the Permian languages use the same device, with the
same suffix, to create the same result as some IE languages? Where
does that leave the IE status of IE *-sk-?
