Your assertion is correct: infected hornworms will continue to feed until they are killed by the parasitic wasp larvae. If you want to ensure that there will be no further damage, you can remove the infected hornworm and place it far away from your garden. This way, the caterpillar won’t damage your crops, but the wasps will still be able to emerge and attack more hornworms.
