In situations like this that I have seen, "less" refers to subtraction. I have seen old arithmetic books and worksheets that didn't use any symbolic notation, with statements like, "Eight and four, less seven, is five" meaning $8+4-7=5$.
I don't know the context of your statement, so I can't say for sure. However, presumably the "current high" is greater than or equal to the "current low," so if the statement means the minimum, then it is trivial. So I think that meaning is unlikely.
