The confluence of the cut at that point in the dialogue, the hand movement looking odd and the change of the tree blur in the window above him all happening at the same frame and no fingers appearing or disappearing, no other artefacts forming at other moments, points to a simple splice, cross dissolve cut to mask that he misspoke.
Let me know if you have any more questions.
