It's just an additional way to gauge sentiment,

while the volume is low on those put positions, open interest is, well, interesting.

One way to use open interest is to look at it relative to the volume of contracts traded. When the volume exceeds the existing open interest on a given day, this suggests that trading in that option was exceptionally high that day. Open interest can help you determine whether there is unusually high or low volume for any particular option.
