It does, but Valek's fighting style is unorthodox. The best way I can explain it is grievous when he fought Ki Adi Mundi. Without the spinning rib cage or spinning hands.

An even better way for Leto to remember him! Perhaps he was soundly bested by Valek and recollects his unique fighting style. I think it would be a bit far-fetched to say that they had become acquaintances or anything like that.
