Drunkard's Walk vs. PMU

When I was at PS1 the other day, I came across Simon Ingram's Drunkard's Walk (2008) as part of a group show by Minus Space in the Boiler Room:

Drunkard's Walk seems to be a poor-man's version of Roxy Paine's PMU (Painting Manufacturing Unit) 1999-2000:

I take Drunkard's Walk to be a commentary of some sort (satire perhaps?) on Paine's work. However, when I watch an interview with Ingram (see below) he makes no reference to Paine's PMU. It would be interesting to hear Ingram's thoughts regarding Paine.
