Most reverbs work this way. They sum the left and right inputs to mono, and the generate a stereo reverb from that. In most cases this is a perfectly acceptable compromise, especially when using simulations of large spaces.
If you imagine a soloist in a big hall, the character of the reverb really wouldn't change noticeably if they stood in the middle of the stage or moved over to one side, largely because they are never very close to the room boundaries.
However, when emulating small rooms that is arguably less likely to be the case, because the sound source will tend to be much closer to the boundaries when placed hard left/right. Therefore the early reflections from those boundaries will usually be substantially different to the left and right, and thus play a much more significant role in shapimg the stereo image of the reverb. In other words, the source position in the room will alter the generation of early reflections in the left and right rever outputs more obviously.
For this reason, some reverbs have 'true stereo' algorithms, so that the generation of early reflections is controlled and affected by the input source panning, which results in a more natural room sound, especially for small rooms.
This 'true stereo' option typically applies to and appears more in reverbs based on the ray-tracing technique, rather than conventional algorithmic or convolution types.
