I know one of the writer's supposed calls them same time twins because they see a litter as siblings not as twins. But horses don't have litters. They pretty much exclusively have one foal at a time in real life (to an extent that even when foals are conceived, one or both will usually miscarry, or die during birth!) Obviously the pony world can have some leeway, but the standard is still one foal at a time in the pony world.

So yeah, if they were born at the same time, they're twins, even if fraternal. The writer is simply wrong in not calling them twins, especially if other fraternal siblings like the cake babies are considered twins!
