This looks like a PDF copy from the GRO, and if so it will be taken from a return sent in by the local register office rather than an original register. I'm not sure exactly what the protocol was, but as there aren't any obvious errors or corrections in this extract, it looks as though the returns might have had to reproduce the numbers relating to changes, but not the incorrect details which had been changed/corrected.
Incidentally, the GRO have indexed this as Heeling Smith; Yorkshire BMD have it as Keeling Smith, which is what the extract shows.
