As far as I know, CS:S always calls the player_team event when a player's team is changed. Every plugin I use caches the team since it only changes on that event, unless there's a new method from DHooks that doesn't fire the event. And frankly, if there's a method that doesn't call player_team, it should still fake fire the event because that will only cause incompatibility with far more plugins, but m_iTeamNum/CS_SwitchTeam/ChangeClientTeam, the three most prominent methods, all call it.
