No, it is not indicating a fast lens. The expression "ISO 35mm lens for Canon EOS" as written makes very little sense. It sounds like a marketeer's slang. Indications of a "fast" lens might be f/1.2, or f/1.4, describing the amount of light the lens allows. You are being very wise to have your doubts, that shows "experience."
"ISO" in the title is used as a common abbreviation for "in search of".
Amazing how some people limit their reading of various terms and then choose to ridicule others over it.
