That is so, because of the way getcwd() is (was orginally?) implemented:
It basically works by looking recursivly on the parent directory, reading
it, and comparing inode numbers.

So let's say, I'm in cwd with inum=10050, than cwd starts by reading ..,
and notices that ``andreas'' happens to have inum 10050, so getcwd() just
learned that the last component is andreas. And it goes so one till it
finds ``/''.

That's why in bash, there is a difference between the cwd as displayed by
bash, and say by ``sh -c pwd'', because bash tracks cd commands, which
make it remember symbolic links, and the standalone pwd does the recursive
thing ;)

And for the recursive reading stuff you need read rights in all
directories leading to the current directory, ...
