It means there are at least 4 not 4. And for sure it never means 4+4.
Depending on the airlines and COS you can often see numbers not higher than 4 , 7 and 9 for all or some classes. COPA is always a max of 4. AA is 7. TA is 9. Other airlines would love to see real numbers like F 12 J 32 Y 185 but they won't.
When things fill up you'll see the lower cost seats in the same classes diminish in availability, e.g. F will stay at 4 while A (lower cost F seats) will go to 2 or 0, J will stay at 7 while D will go down to 4 or 0 , and Y will stay at 7 (or 9 or whatever) while the O's and R's and T's and Q's go rapidly to 0.
