We have to temper the "150 below" rule when it comes to steps, for obvious reasons. There are various ways of dealing with steps - some will incorporate a slot drain; some (for reasons unknown) slip a piecve of DPC vertically between step and masonry; some rely on a generous fall away from the masonry - and it's usually best to choose the strategy best suited to the actual job. It may be a slot drain on one job, and fall alone on the next.
Generally speaking, fall alone is often the best option.
