Miran's and Tom's answers were both correct. Echoing what Tom said, the last roll generally belongs to YOU. More exactly, unless otherwise stated or depicted, the player represented on the near side -- the bottom of a diagram (if there is a diagram) was the last player to roll the dice.

In the left-hand position, the opponent (White) has opened with 62S and Blue has now rolled 51. (That is, Blue has a 51 to play.)
In the right-hand position, Blue first opened with 41T, White replied with 62S, and Blue has now rolled 51.
Suppose, instead of using Nactation, I would have said, "Comparing 62 (24/18 13/11), 51, with 41 (13/8), 62 (24/18 13/11), 51..." that might have confused you, too. Traditional notation does not lend itself as well to concise comments (or to diagram captions short enough to encompass a sequence of plays).
Typically, such a traditional notation comment might be expanded to: "Compare the position where the opponent opens with 62 played 24/18 13/11 and you roll 51, with the position where you first open with 41 played 13/8, and then the opponent rolls 62 played 24/18 13/11 and you roll 51..." Is that clearer? To those who know only traditional notation, perhaps, but it is still necessary to follow the sequences in your head unless you have diagrams.
In other words, I believe you are currently struggling with two unfamiliar objectives simultaneously: (1) learning Nactation, and (2) visually following along with opening sequences.
In the pursuit of (1), this tutorial will help. If you read the caption of each diagram and match it with the sequence that must have occurred to reach the diagram, I think you'll catch on before long!
Cheers,
Nack
