I doubt it is intentional.
You have to remember that these are more like guidelines than actual rules.....
You can see that the 100AP game was supposed to look more like DBA (square boards, no weather, etc). I've run 2 100 AP DBM tournaments (years ago, based on Dave Brown's ideas), and they used 3'x4' boards, weather, etc. Had this odd deployment mechanism where you throwed 2D6 and deployed that number of elements, opponent did the same, repeat until deployed.
Moved up to 200AP (using the Irish rules) for subsequent tournaments because the 100 and 200 AP games seemed to take the same amount of time! At least in DBM it did.
The 200 AP game is pretty much based on the Irish DBM200 rules (which IIRC was based on an American idea), The 100 AP game is straight Phil. I'd be interested in how people are finding the 100 AP game. For DBM it didn't really work, but DBMM might be different.
