Yellow on top: the back and left edges and the two front corners. The back corners' yellow faces back, like headlights.

Your algorithm backwards
F U R U' R' F' R U2 R' U' R U' R'
solves OLL 43
That's why your scrambles are never the inverse of the algorithm: you'd be practising OLL 43 without knowing it. CubeDojo builds a random state with this case and checks it comes out.
