Well we are talking in the here and now and in the here and now Scotland is a part of the UK. Beides I am not arguing that Labour need the SNP to gain power. What I am saying is as we are at the moment a majority SNP in Scottish Westminster seats is no barrier to a Labour gvt. For a Labour gvt to happen though then England is going to need to vote for it - or at the very least the vote would need to be extremely close in England for Scottish members to make any difference. That is just a plain fact.
