That was in the context of the 2014 Indyref, with the main point of contention being whether independent Scotland would remain in the EU or be forced to re-apply for membership (and potentially be blocked by Spanish veto). The context now is that independent Scotland would have to apply, as it will be a successor state of a non-EU member. I think Spain et al. are fine with this since the precedence it sets will be hard for Basque nationalists to follow.
