Bundles and licenses

The Infoworker’s Pro Office bundle is listed as follows on the shopping page:
DEVONagent Pro - 3
DEVONthink Pro Office - 2

What do the numbers after the program names mean? Does that indicate the number of licenses of that application in the bundle?

Those are the major version numbers – today DEVONagent is at 3.4, and DEVONthink at 2.5.1.
