I think he might be thinking about cos(51.827... deg) = 1/phi = .618...
This is probably where he got the starting point for the geometric
sequence (phi = 1.618...)

>>1.62 - 3.24 - 6.48 - 12.96 - 25.92 - 51.84

This is the angle at which the square of the height is the area of one
of the sides (Heroditus).
