I've made a couple of updates to the doc.

I rephrased the definitions of active from "on date d" to "during a time period", as I think this makes the intention more clear. In particular, Type 1 Active is supposed to refer to the most recent observed activity during the entire time period, not on specific dates. However, this doesn't change the meaning or computation of the DAU/MAU metrics.

I also added a short discussion on the difference between Type 1 and Type 2 active, which summarizes bug 1240849, comment 18. This is mainly intended for future reference when we/others wonder why we have two definitions of "active". The central point here is that this only matters for segments that can change, like version, and the decision of which to use should be made on a product-by-product basis.
