Using the guide is only until you have made a groove for the bit to sit in, then you can take it away without the bit slipping.
As for your method of cutting square holes, it would take a long time to drill 4 holes and then remopve the centre, just use and angle grinder or the plunge method on a wet cutter....job done.
