A few things that affect consensus weight happen at random:
* client usage, which affects observed bandwidth, which limits consensus weight,
* the timing and pairing of bandwidth authority measurement, which limits consensus weight,

It's possible that by chance, 02 got a bad measurement a week ago, and 01 got a good one.
Give it a few more weeks, and see if the measurements even out.
