It kinda makes sense. You can burn natural gas to make electricity. You get 0.4 energy units of electricity for each energy unit of natural gas. Heat pump COP is say 3.5. So you get 1.4 units of heating out. Converting to electricity has costs that eat away at that 1.4 units.
Call it a wash.
The big differences are the electric grid can be powered by zero carbon sources. And burning natural gas is a local pollutant. And if you ditch gas you don't need to maintain commercial and residential gas infrastructure.
