Kabuto Yakushi had not discovered how he had lost contact with the three Impure World Reincarnation Ninja under his command, so he could only send other nearby Impure World Reincarnation Ninja to investigate.
If they had simply been sealed, he would naturally not have cared.
Sealing Jutsu was itself one of the ways to counter the Impure World Reincarnation Jutsu.
