The Short stay visa waiver programme is not separate from the British Irish Visa Scheme; it is inclusive and has footnote specific to Chinese and Indian nationals.
While it does allow a visit to Ireland, the short stay visa waiver programme has a requirement that affects those nationalities, the need to have a BIVS endors*m*nt on the visa. Your UK visa does not, as you commented; thus, there is no work-around that allows you to visit Ireland after your trip into the UK.
Note: Chinese and Indian nationals may visit the United Kingdom and Ireland in some circumstances using a single short stay visa issued by either country. Read a longer description of the British-Irish Visa Scheme.
The expanded information from the Irish Department of Foreign Affairs has the detail, as it affects Indian nationals who can travel to Ireland after the UK if the visa is endorsed with BIVS. Without that endors*m*nt, the Irish short stay visa programme is not available.
Note: The astute reader will observe that the Irish Department of Foreign Affairs site (above link) is out-of-date by about 3 years. Accordingly, it should read with a jaundiced eye and for indicative value only.
The UK Guidance is clear and current for the UK only, it does not take up national schemes that the Republic has implemented.
