[ARM website](https://developer.arm.com/documentation/ddi0135/a/Caches-and-Write-Buffer/Data-cache-and-write-buffer/Hit-under-miss--HUM-) contains an explanation of a feature called "HUM" (hit-under-missing).

It seems that "under" can be interpreted as "after" or "follow", meaning that the previous access is a miss, and the subsequence access is a hit. Is this understanding correct? And if, I am wondering is there special context for using the word "under" (i.e., use spatial-relationship instead of time-relationship).
