That's interesting. A similar approach is used by Tibetan Buddhist Monks, and they use the slighlty reclined posture for their 4th cycle of the night (final 2 hrs). They say the same: it's great for increased awareness during this phase.
During the other phases they actually sleep on their right side though as they say it helps with 'energy channels'. Taoist dream masters do the same.
