I don't believe they are contradictory at all, the servers are not connected in the way that you can sail and there is no pvp missed by catching people travelling to and from pve, so the way I see it is like an epic-freedom connection and I am not a fan of mechanics that punish people for picking one or the other. To say that people can "teleport" from pve straight to the deed would only be the case if you were able to sail, the likeness would only be able to be drawn if every time anyone logged out at all they were sent back to the spawn town. Since the two servers are not traditionally joined and no items swap its more like someone logged out to play some other game and then their mates alerted everyone in discord to log in.
To the alternate suggestion of blocking someone from logging in just because there is enemy in local - Who are the enemy to decide when someone can and cant use their premium account? I don't imagine that would equate to happy customers.
As far as skill transfers go I can understand the reason to prevent FS cross over (despite opening characteristic windows) and again just like epic/freedom, faith not swapping (to a degree), but anything beyond that goes back into the punishment of choice and the final nail that was in epics coffin. The more there is a loss from swapping over the more people will stop swapping, especially when the current player base are already being double dipped to participate in the new fun.
