How would you consider a site to be 6.4?

If I had a site that I deploy in AEM 6.4.3 instance, but in the source code I have the following in the pom files:

            <dependency>

                <groupId>com.adobe.aem</groupId>

                <artifactId>uber-jar</artifactId>

                <version>6.2.0-SP1</version>

                <classifier>apis</classifier>

            </dependency>

(Which is really the jar for 6.2)

My site is considered which version of AEM?

My thinking is my site is 6.2 but it kind of works in an AEM 6.4.3 setup. What would happen if I keep using the site this way?
