This is correct. Not only that, but Lenin also took Kautsky's position *against* Rosa Luxemburg during the "mass strike" debate within the SPD.
I'd like to think that Lenin's support for soviet power in 1917 represents an implicit revision of his position vis-a-vis Luxemburg, but does anyone know of any actual texts where he revises his position in favor of Luxemburg and against Kautsky?
