The in-place update section you referenced was added in Solr 6.5. On p. 224 of the PDF for 5.5, note it says there are only two available approaches and the section on in-place updates you see online isn't mentioned. I looked into the history of the online page and the section on in-place updates was added for Solr 6.5, when SOLR-5944 was released.
So, unfortunately, unless someone else has a better option for pre-6.5, I believe it was not possible in 5.5.2.
