Maybe depending on the TOS version, but I'm not sure.

My 520 STF tos 1.02 doesn't turn it off, and I just checked with a 520 
STE (tos 1.62 I guess) :

 - 1 internal drive A and 1 external drive B
 - boot on A, wait for desktop
 - eject A, click on A icon and click on cancel when TOS says it can't 
access disk -> led and motor remain on until a floppy is inserted (no 
timeout)

 - same on B : drive B is empty, click on B icon, click cancel on the 
TOS message that appears -> led and motor remain on until a floppy is 
inserted in B (no timeout either)

So, either TOS 1.00 had a different behaviour (with a timeout) or it's 
the SF354 drive, but for me the common behaviour is the one I described 
above.
