I think he's talking about this (Destiny)

It really takes me like 2+ minutes as evidenced by it taking me 30 seconds to get from the initial thrall room to the end.

Me blowing myself up is an added bonus.

Okay, not to be pedantic about it, but that's not 30 seconds.

True, but it's a lot faster than say, The Last Array or A Stranger Calls or especially The Wakening.

Boost into the Lunar Complex, jump over the Thrall, stick the Wizard, done.

1 Kill, no Deaths. Boom.

Dark Within, Dark Beyond, Exclusion Zone(to a point), Sword of Crota, Fist of Crots--I consider those to be very short, (somewhat) easy story missions, what I trademarked as 30-Second Dailys. Nothing in Destiny takes 30 seconds--not even loading the character screen. So while it's not literal, it's...well, I guess the term is 'relative'. Either way, it's quick Ascendancy.
