Gayot has a reputation for posting answers that imply being very, very familiar with UK visa processes. I seem to remember at least one question on meta that implied they were directly involved professionally with some legal affairs pertaining to UK visas. Thus, Gayot probably had the opportunity either to talk to the relevant visa centre officers directly or maybe even experienced the procedure first hand. I believe that unless an officer directly involved with these procedures is willing to give us a real answer, anything we can say will have to be speculation.

I think what Gayot means is that the immigration officers use a template for refusal letters in which the reason for refusal is given in the form:
I have refused your application for a visit visa because I am not satisfied that you meet the requirements of paragraph(s) [speed code for relevant Immigration Rule]
Where the [speed code] is usually a pointer to the relevant rules and requirements. For example:
Paragraphs V4.2-V4.11 of Appendix V ...
This allows the immigration officers to personalise the template to each applicant's case whilst providing detailed reasons for the refusal.
