Scrutinizer, I see some minor discrepancy in the o/p:
Code:
$ awk '{s=$1; for(i=1; i<=5; i++) {A[$(i*2-1),i]=$(i*2); s=s OFS A[$1,i]+0} print s}' OFS='\t' filename
a1      0       1       1       0       0                     
a2      1       0       1       0       0                     
a3      1       0       1       1       0                     
a4      1       1       0       1       0                     
b1      1       0       0       1       0                     
b2      1       0       1       0       1                    
c4      1       1       0       0       1
d1      1       1       0       0       1

EDIT: I noticed discrepancy even in my join command o/p.

EDIT: Got it fixed after setting the field separator to tab spaces -F'\t'

EDIT: Scrutinizer, setting the field separator to tab spaces for your awk code gives correct o/p
