Yes it can, but you would need to split the first video into 2 videos and
then concat all 3. That is how an insert works (even in a NLE program like
Avid, FCP or Premiere).

Note that all the formats need to be identical and you would need to either
use an intra frame edit friendly format or split on an I frame
