If statement in Pillager Entity is never true

All names are referencing MCP mappings.
In the class Pillager Entity the updateEquipmentIfNeeded method checks if the item is an instanceof BannerItem, else it then checks if via func_213672_b is a Items.WHITE_BANNER which is an instanceof BannerItem, but due to the initial if statement it would prevent the statement from ever being true.

Mojang names are:

• Pillager.pickUpItem(ItemEntity): Which already checks instanceof BannerItem
• Pillager.wantsItem(Item): Which checks for the white banner
