The man page claims something different, or the wording in the info
file is ambiguous:

  -execdir command ;

  -execdir command {} +
	Like  -exec, but the specified command is run from the subdirec‐
	tory containing the matched file,  which  is  not  normally  the
	directory  in  which  you started find.  This a much more secure
	method for invoking commands, [etc]

Here's what happens with find 3.5.8:

  $ find . -name foobar -execdir pwd \; -execdir echo '{}' \;
  /home/corinna/tmp/abc
  ./foobar
  /home/corinna/tmp/DOS
  ./foobar
  /home/corinna/tmp/foo
  ./foobar
  /home/corinna/tmp
  ./foobar

And here what happens with find 3.5.9:

  $ find . -name foobar -execdir pwd \; -execdir echo '{}' \;
  /home/corinna/tmp/abc
  ./foobar
  /home/corinna/tmp/abc
  ./foobar
  /home/corinna/tmp/abc
  ./foobar
  /home/corinna/tmp/abc
  ./foobar
