enter image description hereRespected member, I am new learner of codeml and designing my experiment for analysis of 14 mammalian coding sequence based on the tutorial at

In my analysis, human is “foreground branch”.

I am getting confused with the hypothesis of branch model. image of the Hypothesis given in the link below

My question is in first comparison (Free-ratio vs. one-ratio model), we are already testing if for a tree of s species, is ω different among lineages?

Then why are we doing Two-ratio vs. one-ratio model to test "Are the foreground branches that you specify more likely to have different ω from background branches?"

I think in both the case we are getting same result.

Please help
