Multicast Mtrace output interpretation

As I understand it the mtrace command will trace from the source
specified back to you and show the path that it is taking ?? So this
setup is from IE lab 1 , I am curious if anyone has a good explanation
as to what is actually going on here ? Can you tell by looking at the
output if this means all is good ? What would a bad mtrace look like ??

TIA , Long

r3#mtrace 183.1.0.5

Type escape sequence to abort.

Mtrace from 183.1.0.5 to 183.1.0.3 via RPF

From source (?) to destination (?)

Querying full reverse path...

 0 183.1.0.3

-1 183.1.0.3 PIM [183.1.0.0/24]
