If Ireneaus was a student of Polycarp (a student of John the Apostle), why doesn't Ireneaus interpret Prov. 8 as a reference to Christ?

Ireneaus offers the following interpretation of Proverbs 8, > I have also largely demonstrated, that the Word, namely the Son, was > always with the Father; and that Wisdom also, which is the Spirit, was > present with Him, anterior to all creation. He declares by Solomon : > "God by Wisdom founded the earth, and by understanding hath He > established the heaven. By His knowledge the depths burst forth, and > the clouds dropped down the dew." And again: "The Lord created me the > beginning of His ways in His work: He set me up from everlasting, in > the beginning, before He made the earth, before He established the > depths, and before the fountains of waters gushed forth; before the > mountains were made strong, and before all the hills, He brought me > forth." And again: "When He prepared the heaven, I was with Him, and > when He established the fountains of the deep; when He made the > foundations of the earth strong, I was with Him preparing [them]. I > was He in whom He rejoiced, and throughout all time I was daily glad > before His face, when He rejoiced at the completion of the world, and > was delighted in the sons of men." (Against Heresies, 4:20:3 - ANF > 1:488) If Ireneaus was a student of Polycarp (a student of John the Apostle), why doesn't he (Ireneaus) interpret Prov. 8 as a reference to Christ, especially if we are to believe that Prov. 8 influenced Jn. 1:1? Wasn't Ireneaus from the Johannine school of thought? Why doesn't his interpretation align with what is supposed to be the "Johannine tradition," if Prov. 8 was really the influence for Jn. 1:1?
