The reasons why this mark has national boundaries are as follows:

The reason why trademarks have national boundaries is mainly due to the different provisions and implementation methods of trademark laws in different countries. Each country or region has its own trademark law or trademark treaty in the region. The trademark rights granted by these laws are only valid in that country or region and have no binding effect on other countries or countries outside the region.

Therefore, a trademark registered in a country can only be used within that country and protected by law. If it crosses national borders, it loses the right to protection in that country.
