How much data is cached in the analysis service cache?

I previously thought the amount of data in the analysis service cache was governed by the following parameters:
MinCacheEventsPerAttribute 

MaxCacheEventsPerAttribute 

CacheTimeSpanInMinutes

 

But I found the following excerpt in KB01495:

Starting in 2.9.0, the service dynamically determines how much cached data each attribute needs based upon the analysis configuration and trims appropriately. If the service can't determine how much cached data is needed, the attribute's data is trimmed according to the global configuration parameters (...)

 

What would happen if I'm using the default values for the parameters mentioned above and I create an analysis like:

TimeGT('My tag', '*-1mo', '*', 50)

 

Does it mean the analysis service will bypass global configuration parameters and cache the whole month of 'My tag' PI point?
