Lacking the chance to not get restrained isn't a factor in PK appeals, unless the inability to avoid detainment was a result of prop blocking or some other rule violation. Here, no rule was violated in regards to your limitation in movement.
This is a valid concern with PK appeals. In this situation in particular, there seems to be sufficient RP for a PK to be conducted. The roleplay may have not been the best, though not every seen is perfect, including back-and-forth dialogue for a specific amount of time, a viable chance for escape, etc., but is, nonetheless, sufficient for a PK to occur. An example of a PK scene lacking RP would be one with little-to-no interaction, such as sniping (which require UA approval and only occur under extraordinary circumstances).
