Comment(by nbruin):
Incidentally, from a 2-(isogeny-)descent on E one can conclude that the
rank is 0, so while the upper bound returned does not contradict the
documentation, the code is not returning the appropriate bound.
In Magma:
> RankBound(EllipticCurve([1,a+1,a,a,0]));
0
> AnalyticRank(E);
0 0.359929
but you probably already knew that.
