There is something else I noticed in the interview.
Gerry: Just yeah, so I went outside and I was outside the apartment and I met err one of the other guests and he was coming the other way with his kid and I actually crossed the road to erm to chat to him and we were sort of chatting for about five minutes and during that, Jane went to check on her children and it was at that point she was just passed us going up to the corner and she saw a man carrying a young girl with almo.. she described independently the pyjamas that Madeleine had on and she didn’t see the child’s face she didn’t you know she saw me there she’d seen that I’d just been in the apartment and so she at the time she thought it was something odd but it didn’t raise enough alarm bells to challenge the person or anything

I've listened to the interview, and I think he was going to say 'almost', i.e. almost the same pyjamas.
It is probably not a major issue, but if there was some doubt about the Tanner sighting I'm surprised he did not also take the opportunity to mention the Smith sighting, which I cannot find in the transcript (unless I've overlooked it).
There may have been time limits for the programme which limited the opportunity to discuss sightings.
