Every match in Top 11 is simulated on the live servers of the game, not on the player's local platform (Mobile or Web). i.e. Multiplayer on Top 11 happens via a dedicated server instead of relying on a peer-to-peer connection.
Which means that if a player's connection is lagging behind or some of the data packets are not reaching the target, due to what ever reason, a de-synch may/will occur and an event during a match may not be updated on your local client. This can lead to a different match result during and after the match.

I spoke more on the matter in this post here.
