No. Note that enwiki has many *un*intuitive category chains as well. For
example, you might not expect [[Death Valley]] to be in [[:Category:Bodies
of water]], but it is:
* [[Death Valley]] is in [[:Category:Death Valley National Park]]
* ... which is in [[:Category:Northern Mojave-Mono Lake region]]
* ... which is in [[:Category:Watersheds of California]]
* ... which is in [[:Category:Watersheds of the United States]]
* ... which is in [[:Category:Watersheds]]
* ... which is in [[:Category:Rivers]]
* ... which is in [[:Category:Bodies of water]]
