Narrative:

During my flight to my practice area, a C152 was reported to me at 12 O'clock (2 mi). I confirmed visual contact. I was traveling at 700 ft, heading 270 degrees. C152 was 2 mi traveling 180 degrees at same altitude (he also confirmed visual contact with me). I pulled up, once passing C152 on my left, making a complete 360 degree turn and continuing 270 degree heading. The C152 descended while I climbed, and was way below me, while constantly in sight to me. Cessna reported near miss. I cannot comprehend how or why. The distance at no point was less than 500 ft, in my opinion, and constantly in view. How can someone have a near miss with a plane already seen?
