You got it wrong, read again:
When flying on minimum you don't divert after 30 minutes, you divert instantly if there is any delay at destination.
reaching your alternate, you have a so called final reserve of 30 mins and going into that, you have to declare an emergency.
I sugget you all do some research in the relevant, publically available laws and regulations, then form an opinion and then post. It's like on the radio: Think, Push, Talk...
