It is. I'm not sure why the caption compares it to the SIPA S.11 other than its general layout.

According to Xavier Massé,  the D 4 was to have a 32 cv engine - less than 1/10th the power of the S.11's SNECMA/Renault 125 engine. Of course, Massé could be wrong about the planned powerplant ... that cowling does look rather large!

There is definitely some sort of misunderstanding here.  I can't imagine any circumstances under which a 32 hp engine would be suitable for a two-seat military trainer, especially not during that time period.

Agreed. The cowling looks too  large ... and most 32 cv powerplants of that time are 2-cylinder horizontally-opposed engines like that of the D 5.

My dear Apophenia;

that was my thought from your early reply.

Also from Ailes 12/1944.

That looks like a development of the Joly Motoplaneur or E-1 of 1933. Here's a photograph of that which, I think, has its source in Les Ailes (but, regrettably, I don't have the issue date noted)
