I was told I can trust him, but he didn't go through everything said over here.
If he would, in most cases it would be in vain, as we have gone very technical here. It's almost a sure way to lose a sale and a customer. He's probably giving you a high level answer.
If you want more detail, ask him, but it wouldn't benefit you if you go too deep into the details, you'll be stuck in paralysis of analysis. Doint something that is 80% good, is preferable to not doing something that is 99% good. You've got 3rd party confirmation that the scheduled vs. guaranteed rates on a YRT are not a reason for concern.
Now your question might be if you want a YRT or a level-term product. Ask him to show you both and to outline the advantages and disadvantages of each.
One thing I personally like about YRT is that the premium increases serve as a reminder for the policyholder that it's time to review coverage.
