Yes, it does make a difference to say that the stars pass the meridian every 24 hours, and the stars pass the meridian ONCE every 24 hours.

The first implies that it is done at the same time every night. The second clearly acknowledges that the time it happens changes, but it does not occur more than once every 24 hours.

There are months of the year where it never visibly passes the meridian at all. This is the reality that we must deal with, since the AEs never indicated they knew the stars passed the meridian during the daylight hours.
