Does woolly here mean "confused and vague; used especially of thinking"?

In addition, does "In her biography of Krishnamurti, Pupul Jayakar quotes him speaking of that period in his life some 75 years later" mean "some 75 years later, Pupul Jayakar's biography of Krishnamurti described that period in Krishnamurti's life"?


Context:

In April 1909, Krishnamurti first met Charles Webster Leadbeater, who claimed clairvoyance. Leadbeater had noticed Krishnamurti, on the Society's beach on the Adyar river, and was amazed by the "most wonderful aura he had ever seen, without a particle of selfishness in it."[a] By Ernest Wood, an adjutant of Leadbeaters at the time, who helped Krishnamurti with his homework, he was considered "particularly dim-witted".[14] Leadbeater was convinced that the boy would become a spiritual teacher and a great orator; the likely "vehicle for the Lord Maitreya"—in Theosophical doctrine, an advanced spiritual entity periodically appearing on Earth as a World Teacher to guide the evolution of humankind.[14]

In her biography of Krishnamurti, Pupul Jayakar quotes him speaking of that period in his life some 75 years later: "The boy had always said, 'I will do whatever you want'. There was an element of subservience, obedience. The boy was vague, uncertain, woolly; he didn't seem to care what was happening. He was like a vessel, with a large hole in it, whatever was put in, went through, nothing remained."[15]
