With the boiler at 100 psig and the line at 60 psig, when plant operations pops open a line for process, the boiler doesn't have to immediately follow the demand as the water volume is prepared for the higher pressure down to the reduced pressure. When your supply is at boiler pressure, the firing rate and water feed rate will follow the demand closely with wider variation. Management loves to make everything and everyone work like an insane fire drill. 100 psig is a more dangerous and hotter temperature for operations to be subjected to, so they might be looking to increase their accident rate if they don't really need the extra process temperature.
