The highlighted part is correct and that is what I meant, but
you almost get the second part correct.
The thing is when the poop is transmitted by peristaltic movements,
a certain amount of it will rest in the rectum which expands (after
a certain amount is stored there) and stimulate the nerve ending
for defecation. You will then feel the sensation to poop and
evacuate it. The remainings will take quite some time for the
peristaltic movements to shift its location to the rectum, and as
it is, it stores up and up to a point, the expansion will again
stimulate the nerve endings.
