I think this could be made clearer in that the insertion point is set to the exact same location in the new block.
Maybe something like:

```suggestion
  ///
  /// The insertion point is updated to insert before the same operation as prior to the split.
  /// If the insertion point was at the end of 'block', the new insertion point is at the end of the returned block.
