I'm sure the Buddha had his reasons for requiring that monks not disclose attainments to the laity, and I also take that to indicate that I, as a layman, should refrain from speculating on others' attainments.
"To reach beyond fear and danger we must sharpen and widen our vision. We have to pierce through the deceptions that lull us into a comfortable complacency, to take a straight look down into the depths of our existence, without turning away uneasily or running after distractions." -- Bhikkhu Bodhi
"No man ever steps in the same river twice, for it's not the same river and he's not the same man." -- Heraclitus
