C.C. I think I understand your confusion
When I started out - I won't say how long ago, but fan markers were pretty common and there were very few of those new-fangled VORs about - "Resume own navigation" meant to turn back and intercept the original track at an angle of 30 degrees. The common phraseology now, "Resume own Navigation direct to ....," is just that - fly directly to the position specified.
