@Will_E_Vander Hello Will, its great recommendation. I already know this way to fret. Tommy Emmanuel is doing it always… I can remember I learned that on my first ever fingerstyle song Anouk Lost and last time I used it was in Freight Train, but I did not think about using it here. 
From materials where I am learning that its like this and it makes sense to me, because before F chord shape I am holding just note C (without capo, so its B I guess with capo) and its in good position to “jump” to standard F chord shape without barring high strings, I dont need it here.
