This is not true. You can't run a 64 bit program under 32 bit kernel.

IA-32 emulation is the other way. Here is the definition from kernel config.

IA32 Emulation:
"Include code to run 32-bit programs under a 64-bit kernel. You should 
likely turn this on, unless you're 100% sure that you don't have any 
32-bit programs left."
