In theory you shouldn't be able to restore anything from a modern SSD after deleting stuff.
TRIM will make sure that sectors on the SSD are reset (after the SSD’s garbage collection) to enable fast writing if those sectors are reused.
Still, it might be that some SSDs won't execute the TRIM command but I'm not aware of any from the recent time actually.
So personally I don't think any secure delete actions would be even required nowadays.
But that's just my understanding of the TRIM feature.
HBS will not copy anything that was already deleted unless you explicitly activate "sector by sector backup".
But even then, if TRIM works as I think it does, sectors of deleted files should be reported as zero instantly for any OS so the backup would not have any useful data. And forensic tools won’t help as soon as garbage collection was run on the SSD (which usually takes place rather quickly during idle times).
