Unfortunately Cygwin hasn't integrated FUSE filesystem types into 
'mount' and /etc/fstab. This is why FUSE mounts are recorded in 
/var/run/fuse.mounts rather than in the usual mount table, for example.
The sshfs man page is correct for Linux and other OSs but less so for 
Cygwin. On Cygwin any FUSE mount has a managing process; these are 
sshfs, and when available, ftpfs, memfs, etc. They do the actual mount 
and then hang around in background to support operations on the mounted 
filesystem. The Cygwin DLL doesn't know about these filesystems.
If your goal is to have "permanently" FUSE-mounted filesystems, about 
all I can suggest is to run sshfs from your first Cygwin shell after a 
system boot.
HTH,
