Punctuate

The text below describes the last seconds of the video artwork "Lasso" by Salla Tykkä.

1. Does "punctuate" here mean "the music disperses over the video"?

2. Does "occupies the transversal fluidity between these points" mean "it is fluid between the roles of voyeur and exhibitionist"?

Text:

Again, as in Cadieux’s invocation of the voice, sound is important here. The strains of Ennio Morricone’s soundtrack to Once Upon a Time in the West continue to punctuate Tykkä’s electronic whiteness, creating a generative field of potential in which the subject is neither voyeur nor exhibitionist, but perhaps occupies the transversal fluidity between these points, as in Bollas’s notion of attunement.
