I don't recommend this method of remembering seed phrases in anyway. Just remember one thing that if you forget or don't use something for long period you will forget it eventually. Atleast some part of it. So don't do this.
@OP not only memorizes his seed phrases but also has backup probably hidden somewhere, so he is still playing safe while trying to "brag" about him memorizing the his Bitcoin seed phrases. I don't see any fault in @OP's strategy because he makes sure that there was a contingency plan in case he forgot his seed phrases.
It is good to exercise our brain daily, they say it is healthy because it helps us reduce the risk of memory loss. If @OP does this "ritual" he said daily then probably he may not forget his seed phrases until old age.
