Luminosity masks vs. blend ranges ?

[cgidesign]

Am I missing something, or do the new luminosity masks in V2 do more or less the same like the blend ranges of V1 and V2 but with the exeption that they can be switched on/off and copied in the layer panel?

I was wondering the same. Look at this answer
