If the orientation parameter, o, is either not provided or is given as column, the columns of A are concatenated (from left to right) and a column Vector is returned. When returning an Eigen vector to numpy, the conversion is ambiguous: a row vector of length 4 could be returned as either a 1D array of length 4, or as a 2D array of size 1x4. To create Rotation objects use from_ methods (see examples. vector looks like now, you see there is no difference from the array my.
