Exception in Axis argument of pandas function

As I read in previous chapter of the course that axis = 0 refer to columns and axis = 1 refer to rows but in panda.multiply(discuss in feature section of machine learning course) it is mention that, to operate on rows we need to specify axis = 0 and this contradict the previous statement. So all i want to know that is there any exception in axis while dealing with multiply function of panda.
