No it would cut were ever you paste it down. Most CAD/CAM programs give you as way to copy and layout multiple copies of the same part or bits of it. Bobcad calls it translate others will be different names.!
True nesting you can select multiple parts tell it how many of each and the separation required then the nesting function will either lay them out in a grid or if odd shaped rotate to make best use of the material.
This is great for instance when cutting say different Letters or numbers out of one sheet has each letter will be different shape a grid pattern would be very wasteful. The nesting function will twist and place them to extract the most out the sheet and will even place smaller items inside the waste of another part IE: e from the centre of O.!!
Also very handy if your unsure how many parts you'll get out of sheet of material because it will tell you exactly.!! This is why often nesting is an upgrade or only in the Pro version.

How many do you want to cut.? Out of what size material.?

Has an exercise if you don't mind posting the G-code I'll see if I can make parametric code so you enter required number of pieces and material size along with part separation and the code does the rest.?
