Teodor, 
Yes, there are differences in pattern between them. Nevertheless, the difference are in wootz pattern type in my opinion. 
 
Could it be Russian i.e. Anosov's wootz? Attached is a closeup of allegedly Zlatoust produced wootz shashka blade. There are similarities to your patterns, but still - I do not think these are typical pattern welds. 
 
Ariel, Rick what do you think?
