Is it BND only a TRA, or could it be both a TRA and an INV?

Dears,
I've been using the smoove software for structural variant detection recently, and I have some questions regarding the BND-type results, for example:
chr1 89121966 5132_1 N [chr21:45417197[N 158.48 .

Based on the results above, we know it is a translocation event involving DNA segments. According to the specifications in the VCFv4.3.pdf document, we also know that one of the fragments is joined in reverse-complement orientation to the other segment. Given this, could this event represent both a translocation and an inversion?
