   That's not the case if the tunnel entry point node is not the original
   source node.
   
=> this changes nothing: in both cases there is a route to the
destination and packets will follow it. The difference is they can be
encapsulated or not, the visible source address doesn't matter...

PS: differences can only be in source address based policies (QoS, IPsec,
policy routing, etc).
