ifconfig does strange things if it's used the wrong way.
And that's what most people seem to do...

"alias" is a parameter. Therefore in your example it should be
$ sudo ifconfig xl0 inet 192.168.25.49 alias \
netmask 255.255.255.255 broadcast 192.168.25.49
and
$ sudo ifconfig xl0 inet 192.168.25.49 -alias \
netmask 255.255.255.255 broadcast 192.168.25.49
