Are the game's DLL not compiled with optimization flags on?

[Maegfaer]

Or is the C# compiler just not very good? I encountered this in a decompiled DLL while modding and it seems this is a clear optimization opportunity:

if (partyToReceiveLoot.IsMobile)
{
    TakePrisonerAction.Apply(partyToReceiveLoot, troopRosterElement3.Character.HeroObject);
}
    else
{
    TakePrisonerAction.Apply(partyToReceiveLoot, troopRosterElement3.Character.HeroObject);
}

DLL: Taleworlds.CampaignSystem.dll
Method: LootCollector.GiveShareOfLootToParty
