Because timeshift relies on hard links for file level deduplication and to give you what seems to be a complete copy even if it's using only a fraction of the space because files are linked from previous snapshots. NTFS does not support such hard links but only soft links, which are not as versatile. External ext formatted drives will work.
Sorry, I'm not really an expert in file systems, but NTFS supports soft links, hard links and junctions. The following link has more details. https://superuser.com/questions/67870/what-is-the-difference-between-ntfs-hard-links-and-directory-junctions
Perhaps, neither of these three kinds of links are exactly what timeshift needs to function, but hard links as such do exist in NTFS.
why file systems are not supported NTFS for backup to to external hard drive?
