Not even the trinity doctrine says Jesus is YHWH.
The WT has its own definition, to create a straw man fallacy.
As used by the RC God is a description and a title, not a name. So Jesus is God, not YHWH, or the Holy Spirit.
So yes those verses are speaking of two people- as is Hebrews 1 where YHWH addresses Christ:"your throne oh God is to time indefinite."
Also the verse where YHWH says speaking of himself: "and they will look to me the one whom they pierced" yet it is Christ that was pierced. (In case you are wondering theNWT omits the ME in this.) Two persons again.
