Maybe I don't have a clear idea of what an "inode" is in this context.
I normally think of an inode as a small block on a physical disk.  It
has
a fixed size, say 1K.  A file larger than 1K would span multiple inodes.
Or maybe I have this wrong.

In the case where a file consists of multiple inodes, and a data write
is performed which spans two inodes, does the write get broken into two
raw nodes, and linked into two inode chains, or is one raw node written
and somehow magically shared between two inode chains?
