22.7 Mounting at Boot

In section 22.7, Mounting at Boot, it says to enter SECRET /dev/mapper/MYSECRET but according to the man 5 page for crypttab, I'm interpreting it as needing the first field to be /dev/mapper/MYSECRET and the second to be /dev/sdb7, or the underlying block device. 

It seems that both work so I was wondering what the difference was, if any.

Thanks!
