HI, yes MB does do strange things with blower motors. The Ignition switch on most older cars did have a circuit just for blower motor & nothing else (15X). Since blowers with A/C/C use upto 30A, they deemed that necessary. On later cars like your W140 S-Class there isn't even a fuse for blower & it's not even switch off w/key! In other words circuit 30 directly from Battery! So that rest function will operate w/o key.
