If the oil were haemorrhaging out of the bearings as you state, system pressure would drop...... You need to brush up on your knowledge of hydraulics.
Oil being lost out the side of the bearings is the only way for additional oil to get in, it is by these means that a journal bearing is cooled. It is less desirable for the bearings to not allow some oil to escape, under these conditions bearing temperatures increase and as a result the oil in the bearing loses viscosity and the oil film could break down allowing metal on metal contact.
