My shy attempt:

Confusing comes from what we understand under 'Continuation'

1/ Sylvain's meaning when he states other impl should be possible:
The word continuation has been associated to this notion of 
having frozen execution stacks that can be picked up again.

I guess this understanding goes back to how Christian Queinnec 
started using the word in his paper (haven't read it and the link 
from 
http://www.webweavertech.com/ovidiu/weblog/archives/000179.html 
is dead)


2/  Stephan's meaning when he states: "it is that what we continue"

he's backed up by http://m-w.com
Function: noun
Date: 14th century
1 : the act or fact of continuing in or the prolongation of a 
state or activity
2 : resumption after an interruption
3 : something that continues , increases, or adds


IMHO:
I think the verb 'continue' catches a broader consensus: 
interactions or use cases are indeed just started(initiated) or 
continued, and this also captures the relation the sitemap has to 
this.
The noun 'continuation' has gotten a ring of being tied to a 
interpreted-language implementation.


The inflected confusion from the history of the 'noun' adds up to 
some case against using it IMHO.
