Yes, they are AFK profiles, I leveled at least 3 different boosted to 90 classes using both Kicks Ally Tanaan intro and mine Horde version.
The sole difficulty with using the boosted 90s is the lack of skills+low gear.
That leads to lower survival and dps on the toon in the first hour or two of questing, and couple or several dies, especially if its caster or rogue. The tanks have no such problem, even with boosted to 90 handycap.
A proper workaround for this should be going to SW/Org as soon as you login, and respec on your class trainer, then spec again - that will remove the boosted-to-90 penalty.
Good luck!
Here it is my Horde Intro (Modified Kicks):

The original Kick's Alliance Intro is on his SVN, accessible via the official thread:
Kick's 1-100 Mega Profile Pack or in the Buddy Store.
On the boosted druids I have tested, they were simply moving in bear (as Guardian specced) 24/7, and not real issue here, beside the very first couple of quests, which require some dps, the bear was really hopeless with only 2 skills
