In the name of accuracy (and my general anal persuasion) B747 type aircraft do not have slats. They have variable camber flaps installed outboard of the inboard engines and krueger flaps installed inboard of the inboard engines.
And yes, the B744, and some B747 classics, will stow some of the flap segments to protect the leading interior from FOD.
Usually, the flap handle will not be moved during the thrust reverse procedure, that is, they crew will wait until they are off the active runway before they clean up the flaps and leading edge devices. Because the flap handle is still in the extend position after the TR's are retracted, the leading edge devices will re-extend.
