Well, these 2 defs are also in wog - animated trees.pac from ERA 2 so you get that idea.

Edit: Sorry, it's more complicated than I thought. Let me show you screenshots below.
Left: Vanilla (static)
Middle: WoG main pac (animated)
Right: WoG Animated Tree (animated)

So basically the avlpntr6.def from animated tree pac doesn't make trees animated (becoz it's already animated), instead it change the shape and size of them.
My suggestion is just remove avlpntr6 and avlpntr7 (def+msk+msg) from wog if your idea is elimating animated trees.

Btw, you might also wanna do a file comparison between animated trees.pac and the main wog pac. As I see there are a few mutual files, which might also be considered removing.
Black - same
Red - different
