Decision 2 Edexcel question help!

Hi, on flow-augmenting questions, the past papers all seem to allow routes that go the wrong direction down an arc of a directed network? Is this a mistake in the mark schemes/questions (as they are uploads from 2006ish), or can you go the opposite way down a directed network?

That is how you write backflow in flow . by backing a certain amount of flow down one route you can flow more through another
