No that's a reversed-R which happens to look identical like a Cyrillic letter. I don't think that's a problem any more than getting confused and trying to pronounce a circle in a logo as an "o". In contrast, the text here is trying to look Greek but doing it poorly.
Not really confusing when you assume the intention is to look clever - the more different the letterform you find while it still being recognisable as the one you are replacing, the more exaggerated your effect is without further reducing readability.
(Yes, I know this isn't "just to try look clever", ala 1337-speak, and is trying to make a relevant reference to the cross audience understanding the is relevant to a cross platform executable, but the point still stands about choosing less similar but still similar enough glyphs)
(I might be partially wrong because I've studied Greek many years ago and my memory is not good)
