The wrong sort of "no"

Idly reading the press releases on the Britain in Europe site, as one does, I came across this sequence:

Britain in Europe welcomes Spanish 'Si'
21-Feb-2005

Britain in Europe has welcomed the decision of the Spanish people to approve the European treaty by a margin of 3 to 1.

As more countries approve the treaty, it will become increasingly clear that Britain would be isolated from Europe if it voted against. Britain's relations with the rest of Europe would be thrown into uncertainty and confusion.

Britain in Europe statement on the French referendum
30-May-2005

Commenting on the result of the French referendum, Lucy Powell, Campaign Director of Britain in Europe, said today:

"The result of the French referendum is a huge disappointment. The issues the Treaty seeks to address - the consequences of enlargement, the need for reform of EU institutions and the economic challenges of globalization - have not been answered by the French vote."

Britain in Europe statement on the Dutch referendum
02-Jun-2005

Commenting on the rejection of the Constitutional Treaty by Dutch voters, Lucy Powell, Campaign Director of Britain in Europe said today,

"The rejection of the Constitutional Treaty by a second founder member of the EU means that a referendum in the UK is now extremely unlikely. We await with interest the outcome of the European Council summit in June, but Europe's political leaders cannot ignore the democratic will of these referendums."

The question is, if BiE were so convinced that Britain would be "isolated from Europe" if it voted "no", how come France is not… or Holland?

Are we talking about the wrong sort of "no"?
