Selectivity of olefin cross-metathesis reaction

I'm looking at the reaction shown below which uses a ruthenium catalyst:

I am confused because the ruthenium catalyst which is used in the reaction should be Z selective due to the features on the catalyst because the adamantyl group favours the side bound pathway i.e. the Z isomer and the di-iso-propyl phenyl group blocks the path to the E alkene.
