Sorry about that. Else is used when falling back and since it wouldn't be overridden setting the flag makes no difference so it should look something like this.

hooksecurefunc("CompactUnitFrame_UpdateStatusText", function(self)
    local statusText = self.statusText
    if statusText and statusText:IsShown() then
        if self.optionTable.healthText == "losthealth" and tonumber(statusText:GetText() or "") and not statusText.fontOverridden then
            statusText.fontOverridden = true
            statusText:SetFont("Fonts\\ARIALN.TTF", 16)
            statusText:SetTextColor(0.95, 0.2, 0.2)
            statusText:SetShadowColor(0, 0, 0, 1)
            statusText:SetShadowOffset(1, -1)
        else
            statusText.fontOverridden = nil
            statusText:SetFont("Fonts\\ARIALN.TTF", 16)
            statusText:SetTextColor(0.5, 0.5, 0.5)
            statusText:SetShadowColor(0, 0, 0, 1)
            statusText:SetShadowOffset(1, -1)
        end
    end
end)
