Minor loop holes don't bother me and I can easily overlook these in order to enjoy an overarching good story. The reason that this story was significantly flawed was because even by its own "rule set" it threw any semblance of coherence and congruent nature out at the end, seemingly for the trifling intent of being different.
The fact that "A" had not met anyone in thousands of "lives" that he connected with at a mental, emotional and perhaps spiritual level at such a depth that the willingness to pursue a relationship until meeting Rhiannon speaks volumes. The reflection and decision to pursue a relationship having had so much experience cannot help but have brought a wisdom that was often shown during the film. Yet at the end the challenges spoken of, leading to their breakup, while definitely different and significant if they were to continue their relationship were far from insurmountable. Given the "once in thousands of lifetimes" connection that the film sought to portray between A and Rhiannon, the story broke coherence when the challenge to fight for the relationship through struggle, thick and thin, wasn't even attempted.
So we are left with 99% of a story doing its utmost to portray a 'soul mate' connection, then the last 1% showing (in spite of the inevitable challenges) how easily they and especially A, who purportedly knew the rarity of their connection, threw it all away (before even reaching and experiencing those challenges which at that point existed only in A's imagination). That last 1% destroyed all belief in any of the meaning that supposedly connected A and Rhiannon during the first 99%. Now if they were to show the strength of their connection through both of them battling through any challenges that came their way, that would keep the coherency and genuinely show how "once in a thousand lifetimes" their connection was. By ending it the way it did it just showed how weak, insignificant and illusionary the connection that the first 99% of the film tried its best to portray.
