But it could. With C++ at least you can get your build to break on some comment errors. If you enable Clang's pedantic warnings, or if you setup Doxygen to emit warnings in the same format as your compiler and incorporate Doxygen execution directly into your build, you can get errors and warnings on bad comments.
Doxygen supports documenting function parameters, C++ template parameters, return values then Doxygen and Clang can tell if the name listed for some of those things doesn't match the actual code or if a certain kinds of comments are missing. This won't tell you the documentation is wrong, but it would stop you from adding or removing a function parameters while ignoring documentation comments entirely.
If you want to go crazy you can write Clang plugins using LibTooling and run and code you want and analyze the comments any way you choose.
