Yes, thats correct diglienna,

Here is 2 Lines:

"Jake is going to town with Alexa." <-Jake and Alexa both appear on this line there for the count would be 1 occurance of Jake and Alexa on one line.

Jake is also going with Sam. <- ALEXA does not appear in this sentence therefore I would not want that occurance of Jake to be counted.
