They probably mean that you will ruin your day and your evening by procrastinating at home. The day isn't relaxing even if you slack, and the evening is stressing because you eventually still need do to some work.

On the other hand that could easily be solved by all being in a long group call / chat. But if your coworkers only know email and telephone, then good luck.

People have more than 2 states, not only "working" or "procrastinating".

Yes, but procrastinating in the time slots that you had originally planned for work is still bad for everyone involved.

It's a different thing if you e.g. plan 1 hour in the middle of the day to go for a walk.
