Bug in AI buys?

[snake]

I think I've uncovered a problem in campaign buys for the AI?
My force value is 3750 (German) and I have 4100 points saved up to fix/purchase new equipment later.
My next mission was a meeting engagement against the Belgium Army.
The AI buy was overwhelming to say the least. At the end of the mission, I calculated I would need over 9000 selection points to buy what the AI had bought. Yet, I assumed that in a meeting engagement with a value of 3750 that the AI buy would be roughly the same amount (4000) give or take.

My question then becomes: did the AI calculate it's huge buy based on my 3750 value PLUS the saved 4100 points? That would explain the large purchase power of the AI in this case.
