find command returning paths that don't exist

In Catalina with Xcode installed, if I turn the command
Code Block  sh
find -x / -type f -name slapd-bdb.5 -print 2>/dev/null | head -2

it returns the two files:
Code Block
/usr/share/man/man5/slapd-bdb.5
/System/Volumes/Data/usr/share/man/man5/slapd-bdb.5

However, the second file returned above does not exist:
Code Block
ls -l /System/Volumes/Data/usr/share/man/man5/slapd-bdb.5        
ls: /System/Volumes/Data/usr/share/man/man5/slapd-bdb.5: No such file or directory


Any suggestions on the proper way to use use find to traverse the filesystem namespace without producing non-existing paths?
