Drop the engine and the tip together?

[NewArt]

In the Bentley manual, on the first page under engine removal and installation, they say: "NOTE- Porsche recommends removing the engine and transmission as one unit, then separating the two." Then they go on to describe the procedure of dropping the transmission then the engine separately. Huh?
I've undone all the top part (hoses, connections, etc.) and I've removed the exhaust, so now I'm looking at the underside and the prospect of reaching all those bolts that attach the tiptronic transmission to the engine makes me think that there may be some sense to Porsche's method.
Any thoughts or caveats on this?
