The following two sequences are very different:

make buildworld
make buildworld

vs.

make buildworld
make installworld
make buildworld

The installworld can update a lot of non-source
files that were used to do the first build world.
META_MODE notices such updates and does rebuild
activity because of them.

One more sequence:

make buildworld
make installworld
update some sources
make buildworld

For that the installworld may be the larger
change compared to the source updates as far
as contributions to rebuild activity go.

This sort of thing is likely what you had
happen.
