I am only guessing, but they could be doing a paper review of your claim.
The Going Out activity looks at three things.
Planning a route - this is primarily a cognitive or sensory (e.g. blindness) activity. You are being asked about the problems you would have with working out how to get from one place to another, you do not need to be able to follow the route that you are planning.
Undertaking a Journey - this is to do with mental health issues such as agoraphobia and social anxiety and is concerned with you leaving the house to go somewhere, they will be interested in the things that stop you doing this. You need to show that you would suffer "overwhelming psychological distress" to meet the criteria.
Following a route - This activity about the problems you would have navigating a route. So are there any problems; cognitive, sensory or mental health issues that would prevent you from doing this? This is different from undertaking a journey, in fact, if you cannot undertake a journey then you will not score points for following one and vice versa.
If you have any further questions please come back to the forum.
