According to the Czech embassy in Washington:
Long-term visa is issued as a Czech national visa with Schengen visa properties, i.e. while allowing to stay on the Territory of the Czech Republic up to 1 year, the Long-term Visa grants a possibility of the stay in the Schengen area for a maximum of 90 days within a half-year.
This tells us that your Dutch visa is basically an ordinary Schengen visa when staying outside the Netherlands. Which means you can simply use the regular 90/180 days Schengen rules to calculate how long you're allowed to travel in other Schengen countries. So the answer is a clear yes, the 180 day period does reset over time.
In reality it's nearly impossible for anyone to really enforce this rule since there aren't any systematic border checks within the Schengen area. So it's up to you if you stay honest with the system or not.
