No, they literally copy-pasted the information - just not what you expected: that is the file name of the downloaded installer (without .msi
extension, as normal when you “rename” a file on Windows - it either hides knows extensions at all, or selects only the name without extension on F2).
There is no “English (US) version” of LibreOffice: only configuration (either automatically selected UI language, or manually selected). The installer is common; the binaries are common; only the localization files actually used would differ.
And indeed, as explained in FAQ, without knowing the actual UI language used, it would only be a guesswork.
