Example from the clarinet stave:

Individual stems are clearly needed in the first bar, as the rhythms differ. In the second bar he uses individual stems for the first dotted quarter and then swaps to combined stems. It more or less makes sense in this example, but there are lots of other times where it all seems very random. It looks as if he more often than not uses combined stems in the horn parts, and opposite in the trumpets.
It was probably faster and visually clearer like this with ink and limited space, but with the privilege of using typesetting software I feel I can make this clearer and I am very tempted to use individual stems throughout for consistency. On the other hand, as a pianist I do acknowledge that combined stems do give a slight benefit in terms of sheer reading-speed, albeit on the cost of having a clear image of the voice leading.
Should I, or should I not? Thoughts? Is it nitpicking to even ask?
(Also, I am unsure about the terminology. I'll happily stand corrected if there are better terms for this.
