Because your motherboard allows for the enabling of AHCI on the ICH9.
This is often a BIOS feature you can turn on/off.

I don't believe it's a bug. FreeBSD has a form of "generic AHCI"
support, where for systems which indicate AHCI is available but has no
direct AHCI chipset driver, will fall back to using a generic AHCI
implementation that should work with most all AHCI implementations.
I would say what you're seeing is good. AHCI == good.
