Yeah, I've seen him (and Tekkub) anchor/size things that way, and I really don't understand why. It seems completely illogical, and also inefficient since the same result could be achieved more logically with fewer function calls.

they're*

        -- (1) Unit tokens are lowercase. This should be "boss"..index
        -- not "Boss"..index. In practice, most/all functions don't
        -- actually care, but you should do it right anyway.
        local boss = self:Spawn('Boss' .. index)
        if(index == 1) then
                boss:SetPoint('TOPRIGHT', BOTTOMRIGHT, 'BOTTOM', -5, -50)
        else
                boss:SetPoint('TOP', _G['oUF_BobBoss' .. index - 1], 'BOTTOM', 0, -6)
        end

        -- (2) You don't need to do this. oUF already
        -- handles disabling Blizzard frames.
        local blizzardFrames = _G['Boss' .. index .. 'TargetFrame']
        blizzardFrames:UnregisterAllEvents()
        blizzardFrames:Hide()
end

Other than those minor issues, are the frames actually being created?

/dump oUF_BobBoss4 and "EXISTS" or "DOES NOT EXIST"

You might also want to add some print statements in your code so you can see what's happening as it happens.
