The way I see it is simple. You have 25 drunks at the bar. They all arrived
at the same time and have equal chance to leave. You come back later and two
are on benches, one only 1 block away and another 2 blocks away. The odds
are that one moved one time and the other moved only twice because all the other
drunks are still at the bar and haven't moved. It is not probable that the
two on the benches have moved multiple times and the ones in the bar not at all.

A bar may not be a good example as it is an attraction to draw the drunks
back. If a marker mutates, does it have an attraction to return to its original
state? It not, then my analogy is more sound.
