I agree that is what the card says. However, I assume that most other familiars (that aren't summoned) start in play and are silent on the point on their card. As such, it seems odd to to give the Reanimate the benefit of the same reading.
Since the reanimate is the only familiar in the base game, I think it's dangerous to assume anything about what "most other familiars" will or won't have written on their initial skill card. For all we know, familiars who are intended to begin the game in play will have a line that says something like "This familiar begins each quest in the same space as their controlling hero" on their skill card.
Barring any official errata from FFG, however, I would agree with other posters that the Necromancer needs to summon their reanimate familiar by using an action to get it into play. Given all the other threads I've been reading about how powerful the reanimate is, I hardly think this is an unfair price to pay.
I suppose the CK is going to be out soon and it has 3 more familiars in it (from what I hear) so that will probably clear things up.
