Agreed - there seems to be some confusion about what is actually meant by the term 'Triangulation'.

Since Ancestry.Com customers cannot use the GEDmatch Triangulation utility, I suggest they try the utility on the menu titled, "People who match one kit, but not the other". The same utility also shows people who match BOTH kits, which is what the GEDmatch triangulation utility does, except this one uses the raw data that is uploaded to GEDmatch rather than the matches found by the testing company.
