Actually, it does not (necessarily). If NF is still defined in the END section - which is not guaranteed in all awk versions - it will print the number of fields in the last line/row of the last file in the input stream. This may be different from No. of cols in other lines / other files!
This comment may seem nit picking, but I made it to prevent misconception of how awk works.
