It is most likely just a mod; it is quite common for "alternate reality" mods to continue the naming scheme of the version they are based on / forked from; for example, this mod labels its latest update as "Beta 1.7.7.0" (that is, it modifies Beta 1.7.3 and its first update was Beta 1.7.4, and so on. Sort of like if I'd labeled my own similar mod for 1.6.4 as 1.6.5, 1.6.6, etc):
Another example of a mod based on Alpha 1.1.2_01 which currently labels itself as "Alpha 1.1.11_111-1"; as you might suspect, these mods are fairly common as many people prefer older versions for various reasons and mod them to add their own content:
That wouldnt make sense tho because i have seen the videos but it was published in 2010/2011 and their was sweet berries..
Unless they hacked youtube to say it was posted then.. or something altered time
in the video i saw Nick doing an achivment, the thing is that these were added in a new version 1.6 I think
Because they clearly aren't playing a vanilla version; it is incredibly easy to hack the game to make it claim it is some other version, in fact, it seems to be a quite common request to change the version displayed in the upper-left:
Incredibly common, even, given how easy it was to find this many results, all for Alpha and Beta versions, the most popular versions to mod into "another version" (usually with more than a simple change like the version text). Then you have mods which pretend to be an "official" version like I mentioned before (like if I called my own total conversion mod "1.6.5", "1.6.6", etc).
I mean, how did I make the game think it is "TMCWv5.10" (the code used for this is exactly the same as what Alpha and Beta had, they just left it enabled all the time, unlike newer versions which only show it when F3 is enabled)?
An old Alt+Printscreen screenshot from the development of TMCWv5 (I was too lazy to boot up the game to get a screenshot showing the title bar, I hadn't changed the F3 text yet):
Simple; even with no Java or modding knowledge you could perform a file search for the version string ("Minecraft 1.6.4" in this example) and edit it with a simple text editor (the hardest part would be setting up a tool to decompile/recompile the game):
// Vanilla 1.6.4
// GuiIngame.java
var8.drawStringWithShadow("Minecraft 1.6.4 (" + this.mc.debug + ")", 2, 2, 16777215);
// Minecraft.java
Display.setTitle("Minecraft 1.6.4");
// TMCW
// GuiIngameTMCW.java (equivalent to GuiIngame.java)
var8.drawStringWithShadow("Minecraft " + Minecraft.VERSION + " (" + this.mc.debug + ")", 2, 2, 14737632);
// Minecraft.java (you can also just directly change the original strings, this just allows easier changing of them)
private static final String WINDOW_TITLE = "TheMasterCaver's World (version 5.10)";
public static final String VERSION = "TMCWv5.10";
Display.setTitle(WINDOW_TITLE);
Also see this recent thread, no matter how "lost" an official version is you shouldn't literally only find a forum thread or small YouTube channel mentioning it:
Does Beta 1.5_03 and Beta 1.5_04 even exist? Because I have seen a video by TheNick56 and does the versions actually even exist
Bruh, can I do scratchblocks here?
Anyways, Hello guys, this is me, alphabetlorefan2003 from Scratch!
All I really found about it was this Reddit thread and associated YouTube channel:

TheMasterCaver's World - my own version of Minecraft largely based on my views of how the game should have evolved since 1.6.4.
Why do I still play in 1.6.4?
