Because then if the nut works its way off, so does the bolt? :-)

That's a subject of great debate in the Mondeo world with opinions divided.
Some say that having the bolt head at the bottom means that if the nut came loose then there's nothing to stop the bolt falling out. Others counter that they have never known the nut to come loose so its academic.
My own opinion is that while its best engineering practice to insert a bolt with its head uppermost, there are instances where this is not possible.
One problem with the Mondeo wishbone was that the bolt, if inserted inverted, could foul the gearbox and chafe through. Ford have since produced a slightly shorter bolt which some say is condoning the reversal of the bolt.
The bottom line is that a lot of people do it this way but its your call.

There is no real reason not to do as you describe, many garages do exactly as you describe.
Good engineering practise would be to put the bolt in from the top, but many cars , including fords (escorts and fiestas for a start) put the bolt in from underneath.

The manual says that to remove the near side lower arm the engine needs to be lifted to get the front bolt out. To avoid the engine lift,is there any reason why I should'nt loosen the nut then hacksaw the head off the bolt and remove from underneath? On reassembly the bolt can be fitted from the bottom with the nut on top of the subframe.Thanks.

The bottom line is that, although hell bent on doing this job properly, I loosened several engine mountings but still couldn't get the thing lifted properly - certainly not enough to clear the bolt upon reinsertion.
In the end, I conceded and dumped the thing in upside down. The correct nuts are nyloc jobs - it's good enough if done up tight.
FWIW, I did not hacksaw any of the excess thread off either - there's about 2cm clearance between the end of the bolt and the gearbox. Caution - YMMV!
