The active circuit in the Redmere cables make each cable act like it is a 6 foot cable, regardless of its actual length, as far as signal re-equalization goes. 6 foot length is the design center for "normal" HDMI cables. Either shorter or longer HDMI cables will degrade the signal differently than the transmitter/receiver chips in the devices at either end assume.
If you daisy chain Redmere cables, it is like daisy chaining a set of 6 foot cables. So (1) you lose the advantage the active circuit is trying to provide, and (2) you gain all the problems caused by the EXTRA signal degradation that happens due to the fan out / fan in of wires at each connection point.
As with any case of things that degrade HDMI signals, some folks won't have any problems. But a single, 20 foot, Redmere cable (for example) is likely to work more reliably than two 10 foot Redmere cables daisy chained, or any other such combo.
NOW, each active device in your HDMI path -- your prepro for example -- REGENERATES the HDMI signal at its outputs. So HDMI in and HDMI out are TWO DIFFERENT connections. I.e., the Redmere cables on either side are not "daisy chained". They would only be daisy chained if connected via a PASSIVE connector -- such as a female/female adapter between the two cables, or something a bit more elaborate such as a passive (purely mechanical) HDMI switch box between them.
