PIE finite verbs are particples/gerunds?

from
Décsy: The Uralic Protolanguage

"
4.14 There were no conjunctions in the Proto-Uralic language.
Asyndetic connection of the sentences was the rule. As in English:
Peter comes, John leaves. The conjunctions are late innovations in
every language.
4.15 In the Proto-Uralic language, coordination was the only
possible way to connect two sentences. Subordination is late and of
acrolectic (of written language) origin in every Uralic language.
The wide spread European type (Standard Average European)
subordination came certainly from Semitic (Hebrew, Aramaic) sources
and was conveyed by Church Greek and Church Latin to the mother
tongues of Europe (in East by Church Slavonic). Originally, all
Uralic languages used gerund- and participle-like constructions
("verbalnouns") for the expression of ideas customarily represented
today by clauses (subordinate sentences). See DECSY 1988.111-112.
"

The finite 3rd person Uralic forms are also "verbalnouns". Therefore
its 1st and 2nd person might be too. And since they are similar to
the endings of PIE, those latter may also be "verbalnouns", as I
claim.
