Sorry, I wasn't clear: I know that orb effects are identical in dota 1. I am saying that many of the quirks of dota 1 have been carried over to dota 2 - Skadi's orb interactions is one example of that.
One difference, for example, is the interaction between naga siren's net and manta style - in dota 1 it dispells the net, but not dota 2. There are subtle differences like that but they are the exception.
