No this is not what we would say is "consequtive yellow"; whereas you are correct that the driver will pass a signal at yellow reading up the the approach released signal (initially at red and then clearing to its relevant aspect- which may or may not be yellow), the first signal will have been replaced to red before the next signal clears so that they are never simultaneously at yellow.
