Strip addresses are 12-bit fields densely packed into 32-bit words. This means that some strip addresses cross 32 bit boundaries. Since every 3 32-bit words will contain exactly 8 strip addresses, the pattern repeats every 3 32-bit words.
This structure maps out how the first two strip addresses and part of the third address fits in the first word of this three word pattern.
See also _TKR_8strips1_bf and _TKR_8strips2_bf, which gives the mapping for the other 2 words
