That would be true, but you stated the converse - not that you will only
need to reboot on a "dist-upgrade", but that when you do "dist-upgrade" you
will (generally) need to reboot.

The latter entirely depends how often you do a dist-upgrade.  I do a
dist-upgrade _every day_.  I rarely need to reboot :-)
