Yes. The term Biodiesel is often used in a confusing manner. Many times people refer to Biodiesel, when in fact they mean a biodiesel blend. Here's a definition from the Biodiesel.org FAQ:
Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats which conform to ASTM D6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. Biodiesel blends are denoted as, "BXX" with "XX" representing the percentage of biodiesel contained in the blend (ie: B20 is 20% biodiesel, 80% petroleum diesel).

Biodiesel in low concentrations like that will have a very positive effect on lubricity. I can't recall if a concentration that low will have much of an effect on emmissions. I doubt your customer will notice a difference in terms of exhaust irratation at this low a concentration.
As far as why so low, you would have to ask them, but the two biggest reasons are probably cost and cold weather issues. B100 is more expensive than petro diesel, so as the concentration goes up, so does the price, and B100 gels at a higher temperature so that's another issue that needs to be dealt with.
