Because that where the mouse is as shown by the lsinput output.

Run lsinput and choose.
Here ia another example:
# modprobe sermouse
# ./inputattach --daemon --mouseman /dev/ttyS0
# tail -2 /var/log/all

Here above we can see the middle button pressed, the mouse moved, and
the button released.

With the above example we can check if that is true.
Another way to test this is to use xev. Start xev, move the mouse xev's
window, press button, move, release, check the result:
ButtonPress event, serial 33, synthetic NO, window 0x3200001,
root 0x4d3, subw 0x0, time 243503614, (56,88), root:(360,300),
state 0x0, button 1, same_screen YES
MotionNotify event, serial 33, synthetic NO, window 0x3200001,
root 0x4d3, subw 0x0, time 243504966, (57,88), root:(361,300),
state 0x100, is_hint 0, same_screen YES
MotionNotify event, serial 33, synthetic NO, window 0x3200001,
root 0x4d3, subw 0x0, time 243504989, (59,89), root:(363,301),
state 0x100, is_hint 0, same_screen YES
MotionNotify event, serial 33, synthetic NO, window 0x3200001,
root 0x4d3, subw 0x0, time 243505012, (60,90), root:(364,302),
state 0x100, is_hint 0, same_screen YES
ButtonRelease event, serial 33, synthetic NO, window 0x3200001,
root 0x4d3, subw 0x0, time 243505908, (60,90), root:(364,302),
state 0x100, button 1, same_screen YES
