??? ABE VS Chrome`s Site Isolation

I found the Site Isolation described in below links is a little bit similar to ABE in concept.
App Isolation and Chrome`s Site Isolation

I wonder whether the ABE rules are similar to the 2 key properties in multi-browser?
-ABE: Accept from Entry-Points
-ABE: Sandbox from Outside-Isolated-App

PS: I`m a crazy NS-fan
