Microwaving two things at once

[myflabberisgasted]

Last night my DH had a Indian microwave meal for tea after he had come back from work late.
The rice took two minutes and the curry took four minutes, he put them both in together for 6 minutes.... I have never thought to do this before!

Was he ok to do that or should they be separate?

I would have put the curry in first for a couple mins, then added rice for a further 3/4 mins.

If ready meal when they come in a pack together you have to blast them together?

Microwaves are great.
