Actually, it applies to several countries. The example given was just one of several cases in several countries. What I am looking for is an ICAO clarification such as in the document provided earlier as it seems to be the new worldwide method for most countries except the US.
As for the subsequent clearance, it was a simple descend to 6000' but there was one or two published altitude restrictions in between.
I suspect that it is incorrect terminology being used.
Thanks
