I doubt that's the issue, because presumably such a result should be from either:
1) a DIMLFAC setting other than 1, or;
2) Dimensioning in a different UCS from that of the dimensioned objects.
In either case I would at least expect the ratio of their intent to their result to be the same for both Offsets, but they're very far from the same. But maybe you're aware of another kind of setting that could result in what they're seeing.
[By the way, I haven't been able to reproduce that kind of result. I wondered about ORTHO being off as a cause, but that doesn't do it for me. So I agree -- a sample drawing that demonstrates this behavior would be helpful, if only to narrow down whether it's a problem with the drawing file or with their AutoCAD.]

I can reproduce this following your example. But instead of hitting return to accept the Through option, type in 1, then when you can use the multiple option and it will work as expected.

When you type in a distance, you don't get the Multiple option displayed in the prompt. Yes, it lets you Offset multiple objects, but separately selected [whether the same one repeatedly or separate objects], and all at the same distance. EDIT: no Multiple option immediately after entering the distance, but one more step in [after selecting the object] you do get the Multiple option, but it does all at the same distance from the previous result [in that direction -- you can go both ways].
I think they're using the Through option with Multiple sub-option in order to get the same object [selected only once] Offset at various different distances. @Anonymous , is that the case?

It works as expected for me [Acad2019] in your drawing. Might your Offset command possibly have been UNDEFINEd, and you have a differently-defined replacement Offset command?

In case it gets you around the problem, you might be interested in OffsetRunningOptions.lsp, available >here<. It lets you change the Offset distance in the middle of an Offset command, rather than having to end the command and start it again to set a new distance. [It does what I wondered about before -- Undefines the native Offset command and makes its own new definition, which is why the result doesn't have all the current possibilities -- it was written under an older version that didn't have as many options in native Offset.] But it's not a perfect solution for what you're trying to do -- you would still need to select your original object again for each new distance.

That correct answer does work just right for me, without Object Snap Tracking on, with the one meaningless difference that the last-mentioned Enter gets the <next object> default and puts me back to the select-object prompt, and it takes one more Enter to end the command.

With through I keep getting the same error. It is because the through option is using the location of the cursor to define the distance. I think a better way is to use MULTIPLE first, then OFFSET. See video attached

Only when you pick with the mouse. In the procedure laid out, the cursor location determines only the direction from the source object [to which side] where the result will go, but the typed number is the distance [at least, for me].
