It may be surprising that the first row of the order matrix is interpreted as degrees. That's a Singular thing, I guess. However, note that since sage-4.7.2.alpha1 Sage finally has "proper" weighted degree term orders - that was trac ticket #11316. So, it will be in the next release. > sage: (x^2).degree(x) > > >>>> 2 > > I didn't find the docstring helpful on this. No? I find it rather clear. If the optional parameter x is provided, then p.degree(x) is the degree of p in x, while it is the total degree if there is no optional parameter. And of course, x^2 has degree 2 in x, but has total degree 2 times the degree of x (thus, 6). Do you have an alternative wording for the doc string?
