That's because (as the man-page states) the parameters to rfcomm bind  
are:
rfcomm bind <dev> <bdaddr> <channel>

Where <dev> is the number of the device node you want to use (e.g. 0  
for rfcomm0).

If you give the command as you do the rfcomm tool will interpret your  
bdaddr as the device node number (atoi(00:...") will yield 0) and 1 as  
the remote address (which is why you see "01:00:...") and use the  
channel 1 which is the default when no channel has been specified.
