It depends on which gate you are going for; if you do not round one; and then stray into the other 3 BL circle then the onus switches as you are coing from the "wrong side"; IMO this rule has been worded very carefully to try and ensure people come from the "outside" of the course to each side of the gate (so they gybe round the gate).

Read the linked thread; we went into it in great detail.
