No problem, the difference is that mashing involves mixing adjuncts with say a highly modified malt like 2-row which is loaded with enzymes that will convert starches in the rice into a viable food for yeast
Steeping only acts to extract color, flavor or sugars that are already in the adjunct, say like crystal malts because they were already converted before or by being roasted/toasted etc etc
Hopefully my wording is correct but thats the gist of it
Edit: also you mentioned munich, that grain is already malted, by steeping you would essentially be performing a mini mash because munich has enough enzymes to self convert where as flaked corn, wheat or rice do not, they are adjuncts not malt
This makes sense to me. I supposed rice could be "mashed" by adding the correct enzymes minus the additional grain?
