A summary of my understanding of 
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h2-Mouse-Tracking:

SET_VT200_MOUSE (1000) is for button press and release events.
SET_BTN_EVENT_MOUSE (1002) is for mouse move events while a button is 
pressed.
SET_ANY_EVENT_MOUSE (1003) is for all mouse move events.

Specifically, the section "Any-event tracking" makes the distinction 
between 1002 and 1003 clear. A direct quote:

Any-event tracking

Any-event mode is the same as button-event mode, except that all motion
events are reported, even if no mouse button is down.  It is enabled by
specifying 1003 to DECSET.
