It's not. This is talking about a person with a robe dipped in blood. That wouldn't be Jesus since he's never described that way. This is YHWH.
Isaiah 63
1Who is this coming from Edom,
from Bozrah with crimson-stained garments?
Who is this
robed in splendor,
2Why are Your clothes red,
and Your garments
like one who treads the winepress?
3“
I have trodden the winepress alone,
and no one from the nations was with Me.
I trampled them in My anger
and trod them down in My fury;
their blood spattered My garments,
and all My clothes were stained.
Not related to Revelation 19. Jesus is not the word (logos). One is an it, the other is a person.
Revelation 1
9I, John, your brother and partner in the tribulation and kingdom and perseverance that are in Jesus, was on the island of Patmos because of
the word of God and my testimony about Jesus.
Regular humans share the same title so it isn't something that just plainly shows Jesus is God. The rest of the Bible's testimony regarding God and Jesus should be taken into account, especially where it's plain they are not the same person.
Revleation 21
22But I saw no temple in the city, because
the Lord God Almighty and the Lamb are its temple.
