This should be clearer, hopefully, when I translate "probability" in arithmetic. If Glak is Löbian, then it has the same physics than us

What does "same" mean here. Same coupling constants?...same number of Higgs bosons?...same spacetime dimensions?

If those notion depends only on the physical laws, they will be the same. If not, they will appear to be contingent or geographical.

For example, if all the hypostases would collapse into classical logic, (which does not happen!), then physics would have become trivial. Everything would be geographical, and comp would have predict the accessibility of worlds with ... different coupling constant, different number of H bosons, etc. Incompleteness prevents the collapse of the hypostases, and thus save physics from being just a sort of geography. Comp saves the "laws" in the "physical laws".
