*Older* 64-bit systems often installed 32-bit support libraries by default.
That is, in the "early days" of 64-bit systems, there were still 32-bit
binaries in use. Or at some point you installed some :i386 program and it
pulled in the 32-bit support libraries.  Or something combination.  Or when 
you installed this package on those machines, way back when you knew to 
install the 32-bit libraries, and just forgot.
