The "guidance" bit in this context is tied to "when they should be in the office".
For the people who prefer to be in office a few days per week, it would be nice if those few days also overlaps with the in-office days for the people they wanted to meet in person, and it's easier to make this kind of coordination at a higher level. Thus management guidance is basically "let's pick these day(s) of the week where our team would try to be in the office together".
