The technical reasons are very simple. If a new system call is
created, and programs use that new system call, then if you do an
installworld before you boot the kernel, that can result in binaries
not working. This has happened with important ones like /bin/sh in
the past. In addition, if you aren't running single user, many
different races exist in the installation process that can result in
bad behavior. There are also potential problems with symbols in
there's a large jump between the revisions being updated.
Usually you can get away with it, but if you want to be safe, you must
do the install in single user. Usually, however, has lead in the past
to problems, which is why the project recommendations are
conservative.
