I thought that OpenType is quasi an extended TrueType. Wikipedia says: "OpenType Filename extension .otf, .ttf". So it isn't obvious why one schould not mix the two parts in one directory.
OpenType can internally use TrueType outlines or PostScript outlines (different algorithms). OpenType with PS outlines normally use the .otf extension; OpenType with TrueType outlines are valid TrueType fonts and therefore normally use the .ttf extension. But OpenType fonts are never valid PostScript fonts. By far not every TrueType font is OpenType compatible: OT-TT fonts have their characters encoded in Unicode and may use OT features; "normal" TT fonts often use default/custom one-byte encodings. The ordering in the TeX tree is probably a matter of taste, but you would even more confused to find .ttf fonts within the "truetype" as well as "opentype" folders, for you can't know (without tools) what's really in the font's guts. And don't you think it would be questionable to draw a line between Unicode encoded TrueType fonts with and without OpenType features? Greetlings from Lake Constance!
