What if the same private key shares two r values that are (almost) identical to each other? Does this help calculating the private key in any possible way?

Suppose r1 = cabc3692f1f7ba75a8572dc5d270b35bcc00650534f6e5ecd6338e55355454d5
             r2 = cabc3692f1f7ba75a8572dc5d270b35ba54694a2d2302093d8b0a93ed5d83f2c

Here r1 + r2 from the same private key shares only their first 128 bits.
