This is traditional Unix behaviour.  The original dirent structure (which
was actually struct direct from <sys/dir.h>) directly matched the contents
of the directory file on disk, and an entry was deleted by setting d_ino
to zero.  Modern implementations of the dirent functions hide this detail
from the user and never return entries with d_ino == 0 any more.
