Are you sure the monk was "walking" instead of "standing"? To put the body into motion, one would need to breathe oxygen to generate energy for the muscles to move. But one stops breathing at the fourth jhana according to SN36.011 (ref:http://www.accesstoinsight.org/tipitaka/sn/sn36/sn36.011.than.html ):
"And I have also taught the step-by-step cessation of fabrications. When one has attained the first jhana, speech has ceased. When one has attained the second jhana, directed thought & evaluation have ceased. When one has attained the third jhana, rapture has ceased. When one has attained the fourth jhana, in-and-out breathing has ceased"
While practicing walking meditation, my breathe becomes very refined and slow. I am not denying from an outside perspective that in 4th jhana the breathe can not be felt or measured, but that does not necessarily mean the breathe has stopped completely. Strong developers of pranayama are able to be buried alive for days because of how much their breathing has slowed. I'm assuming that mind objects take a considerable amount of energy and therefore oxygen to sustain at a constant pace. It doesn't seem so far fetched that someone could still be in motion while their breathe is seemingly non-existent. Though this is all just speculation, considering all I'm basing this on is a small part of a sutta.
