I agree. This design relies heavily on color recognition. The current design adds a spatial dimension that is missing in this design.
Presumably, the illustration on the far right depicts an example of the "green" animation near the beginning of its cycle with perhaps only a half-second having elapsed, the middle illustration depicts the "yellow" animation which further clarifies how much time is remaining by adding a numeric countdown, and the far left illustration depicts a "red" animation displaying how much time remains until "green." Being "half-full" is a state which all three colors can exist in and is not exclusive to "red."
