That's right.  But I don't think the difference is so unimportant with
respect to the current issue.

Also, the difference in the code length shows how the Cocoa/GNUstep
port oversimplifies the whole text input processing: it doesn't
respect attributes in the marked text (which corresponds to text
properties) or the selected range value.
