Drivers run by 32 and 64 bt code at same time

Installed MS Vista U Beta 2 x64:

How can a driver have components in both System32 folder and SysWOW64 - does
that mean the component is being run by both 64 and 32 bit code at the same
time?

Drivers on 64-bit Windows Vista must be compiled to use 64-bit code.

Both 32-bit and 64-bit software can access and utilize that driver using the
Windows API.

I've seen situations where the software\UI is installed as 32 bit but the
actual driver is 64 bit.
