The number of congregations has never been a statistic that JWs have especially trumpeted
I live in a very very multicultural and multilingual land. Over here, the growth/numbers of other/foreign language congregations have always been trumpeted (as opposed to the mainstream language congs). It is commonly perceived here as a sign of interest among the speakers of those languages, and the fact that no one is left out of their preaching effort. The last talk in the assembly always highlights their new groups/congregations/circuits formed, as well as the assemblies held by those new congregations (especially if it is their first).
That said, one constant with the watchtower is that it uses different politic tactics to fit different contexts (we're talking about a global organization here). They maintain a system which benefits their interest until they find another way to maximize them.
So, no, the two realities are not mutually exclusive.
