Yes a "look" is basically determining what algorithm to apply to the cube based on the current state.
1 look last layer means that after the first two layers are solved, you would know an algorithm to apply to solve the cube based on the state of the last layer.
With the typical speed solving method (CFOP), the last layer requires 2 "looks" (one for orientation of the last layer, one for the permutation)
