Takito Double Teapots with Ceramic Base

This is interesting because it contains two almost identical teapots (slightly different floral patterns, quite different spouts, and one is missing its lid) on a ceramic base that is molded to fit the bases of the teapots.  It's from Takito and has the typical Ts in diamonds, surrounded by Hand Paint Made In Japan, at the bottom of each teapot and the ceramic base.  The design is floral with some gold trim on the handles, tip of spout, and tops.  The glazing on one has cracked.  I've been looking and can't find any double teapot sets like this - why would a set come with two identical teapots on a base, anyway?  The spouts are also very different - are they both teapots?  Is one for coffee?  The ceramic base also has a floral pattern that is shown when the teapots are lifted up.
