The only difference is the reduced model, which in one case has the interaction. It's then a matter of what exact question you want to ask. A reduced model of "~replica" will give you "all hours dependent changes, including those only occurring due to a hours:replica interaction", while the "~replica+replica:hours" excludes the aforementioned interaction.
