bach is specifically reffering to an unknown "power" uryu has. That allowed him to "resist" or "null" the effects of Auswahlen. Bach was fully aware of uryu and was astonished he survived, he was also fully aware of the karuosaki children yet did not acknowledge their case of survival as anything exceptional. this suggest that uryu's survival was unique and not the mere luck of being too young or dormancy. furthermore uryu is the only one to which bach bestowed the title "last" "Quincy" (of the earthly quincy who fell to auswahlen).

This likely suggests that uryu already had a soul signature that identified as "Quincy" at the time and already possessed some innate Quincy abilities at the time even without formal training(subconsciously using a power that saved his life) Therefore uyru WAS eligible to be Reaped by the Auswahlen and had to survive through some unknown "power" while the kurosaki kids were not eligible for reaping and survived through dormancy.
