Leave the turntable running?

Hello all, I am brand new to the world of vinyl - just bought a Rega RP1 and Brio-R on Friday. In the RP1 'Hints, Tips and Upgrades' sheet, it states:

'Leave the turntable running during a record playing session. Switch on before the session and only switch off after you have finished. This will increase the life of the motor and drive belt.'

Does this mean leaving the platter turning while 'flipping' and/or taking an LP on/off the table???

Thanks in advance for any advice/clarification!
