I'm not convinced for you have not shown where the pathway is . "the pathway opposite the pool in the Tapas complex." show it on a map please. 
Can you see the path here?
What is your point in highlighting those words Sadie?
No, the path is just off the map to the right of the image. I don’t have the technical know-how to show it on a map and post it. The reason that I highlighted those words is that i think in his own "language" he is stating that he came out opposite the Tapas Reception after leaving the paths to the east via the little car park
OK Rob, I will try and explain my thoughts, even though I am not good with words and explaining, but here goes.
Using the numbers on the image.
Immediately across the road and to the left of number
3 is what we call the Tapas Reception
Immediately below number
3 is what I call the “Little car park”
Jez is confusing to follow and I think that is partly because he has little concept of distance ... but also because he uses different names for places to us... so his language is different.
I am doubtful that he ever used the Tapas Restaurant or Bar, It is quite likely that together, he and Brigette only used the pool and sun bathing terraces around the pool. I am thinking that in their eyes, because to them, together, only using this area they only called it the Pool. That they might talk about that entrance as “The Pool” rather than "The Tapas".
Thinking about myself here hypothetically
If I were hypothetically directing someone locally with our town swimming pool as one of the important reference spots, I personally would not say “go the Swimmiing Pool
entrance and then turn left” I would abbreviate this to "go to the Swimming Pool and turn left"
I think that he is referring to the “Tapas Reception” as “The Pool”
I also think that when he refers to "the pathway opposite the pool in the Tapas”, he is referring to the north south footpath (off picture but to the right) that comes out into the “little car park”, which is shown just below number

The gate which Gerry left is hidden under number
4 …. And the place that Amaral , Jez and Jane say the Jez/Gerry chat happened is at the entrance to the path/alleyway immediately to the left (west) of the TOP of number
3In other words, as you can see from the image, the chat took place roughly half way between where Jez was when he first sighted Gerry and where Gerry himself was at that time.
Hope this helps.
AIMHO, but I know that it is possible that I could be wrong.
