That is because the EU database law does not allow you to restrict the 
extraction of insubstantial amounts of data, see:

http://wiki.openstreetmap.org/wiki/Open_Data_License/Open_Issues#What_is_a_substantial_extract.3F

Also see the document "gradeDigitalRightsIssues" linked from there.

It is not as easy as that; but I think the OSMF (or we the mappers!) 
should write down guidelines about that to go along with the license. I 
am especially unsure about cascading substantialness (if you have an UK 
extract then London might be substantial but is it still if you have a 
planet file?).
