Hmm, so it's cd that's 'at fault'...
Here's a snippet from the NetBSD sh(1) man page:
pwd [-LP]
Print the current directory. If -L is specified the cached value
(initially set from PWD) is checked to see if it refers to the
current directory, if it does the value is printed. Otherwise the
current directory name is found using getcwd(3). The environment
variable PWD is set to printed value.
The default is pwd -L, but note that the builtin cd command
doesn't currently support -L or -P and will cache (almost) the
absolute path. If cd is changed, pwd may be changed to default to
pwd -P.
