Because this can persist beyond an OS rebuild or patch. You infect the BIOS and you're on the device until the BIOS is free reflashed. And who ever does that?

Or until you overwrite that malicious logo again?

No. The logo is loaded, runs in BIOS context and is able to modify the BIOS. Now it's embedded and the logo is irrelevant.
