It means constant readjustment and unnecessarily bloated diffs every time you change a function or variable name.
or the lovely
foo := a;
bar := b;
then a day later foo := a;
bar := b;
foobar := cd;
which also points to the problem that it lends itself to premature constant readjustment because a day later you have to move every thing again because as it turns out you really needed foobarlist as well. and each time you end up with a diff reporting that foo and bar (and then foobar) have changed too.It's making busy work for yourself and ruining the usefulness of code review tools.
ALSO alignment vs indentation is the whole reason we have to have the spaces vs tabs argument.
