Actually, no.
This passage doesn't say the Apostles somehow became infallible; it DOES say that the HOLY SPIRIT will guide them to all the truth. It says HE will speak and tell them (the Apostles) what is yet to come. The passage says that the Holy Spirit will glorify Christ because all that belongs to the Father belongs to Christ.
Says NOTHING about the Apostles suddenly becoming infallible.

The Apostles who wrote Scripture absolutely were infallible in writing Scripture.
I didn’t say it was actually. I said something like that. Seems to me that being guided to the truth by the Holy Spirit is a pretty good thing.
It actually shows that the apostles were NOT infallible. They wouldn't need to be guided into all truth if they were infallible.
