I must admit i can't really see the ambiguity. They are esentially 2 separate phrases.
"after koksi dct bambi. climb FL350" and restriction would have to be specified very specifically
and agree that "now" should only be used to emphasise a slightly more urgent situation (but not one that requires use of "expedite climb"etc) or one where for example an aircraft was initially given "descend when ready FL210" and one changes ones mind (for whatever reason) to "descend NOW FL 210"
Think you need some radar experience Gonz
