Currently it seems that batteries are an expensive technology. And we have limited capacity for their production. So having plug-in hybrid EVs (which can run on batteries for most everyday journeys) or cars running on (green) hydrogen means that sufficiently more greener vehicles can be produced such that more emissions can be avoided sooner than if the focus was battery EVs. Furthermore, BEVs are heavier and cause more road wear (some wear scales with the fourth power of the weight over an axle)
