Yes, but it would be a more natural way to express that two transitions run in the same interval, to use the same duration value; and they'd also start and complete at the same time.

In other words, can't the equivalent functionality be achieved with just step-start and step-end? David Singer Multimedia and Software Standards, Apple Inc.
