It is all in the thinkpad-acpi docs.  The EC (sometimes the AML or SMBIOS
code) does it.  AFAIK, the behaviour exists to avoid issues with
double-hibernation or some other crackpot bug.

It is of no consequence if you use the Fn+F4 and Fn+F12 keys for what they
were designed for (sleep and hibernation).

Nothing to see here, move along ;-)
