That's by design and it is typically what live performers might do as well, the "middle choruses" often being the area where musicians take solos, they are usually then accompanied in a different fashion than for the head and tail of the song "intensity" as you call it, but there are actually musical terms that exist for the description, depending upon genre. For example, in a jazz piece, the middle choruses would swing harder, incorporating more walking bass. Or in a rock tune, the middle choruses might have more push with a bit more from the kick drum and bass player.

That feature can be turned off in the Prefs section as already mentioned above, although I for one usually appreciate it, there are certain songs where you may not want that to happen and its nice to have the choice available.

Here's how it works in BB: No matter what the part markers indicate on the chord grid, for the middle choruses it is ignored and the entire run-through is played in the B substyle entirely. B substyle is indicated by the Green blocks on the bar numbers in a song. A is blue. Middle Choruses are always played as B unless you stipulate otherwise.

It really depends upon how each particular style is programmed whether or not that B substyle has more "intensity" or not. In some instances, it can even change the feel entirely, such as the Dolphin styles where the A substyle is a Latin thing while the B substyle is flat out Swing. That's the way Green Dolphin Street was written. Having the ability to change that way is essential to perform that song. There are other examples, not in the jazz genre, I just can't think of one offhand right now.
