1. yes, dot effects dont apply the buff, only active abilities ( karthus defile or anivias ult wont apply the buff either)

2. the 5% cdr is for better calculating what items u get for max cdr, most aps pick 4 points in sorcery and have 4% cdr at lvl1, and usually take 2 15% cdr items (dfg+athene), so that they have 34% cdr, but there is no 20 % cdr item (nashor doesnt count for real aps), so they have to get a 5% cdr item, or get cdr runes (what noone except me does like it seems)
