Install repeatedly wants to update ITKR

[muratmaga]

I have a new system that I am installing R ant ANTsR. I am using the devtools::install_github() method.
after devtools::install_github('stnava/ITKR') successfully completed, I ran
install_github("ANTsX/ANTsRCore')
which wanted to update the ITKR (sorry the terminal buffer wasn't long enough to capture that. But it looks like below).

I was worried that the versions are not the same, so I said update that as well.

Now I am at the ANTsR stage, and I am getting the same message.

install_github("ANTsX/ANTsR")
Downloading GitHub repo ANTsX/ANTsR@HEAD
These packages have more recent versions available.
It is recommended to update all of them.
Which would you like to update?

1: All                                         
2: CRAN packages only                          
3: None                                        
4: ITKR (186128b01... -> bd0e22647...) [GitHub]

Obviously I can say None and skip, but I am wondering why the default install method thinks, ITKR needs updating. Particularly given that it just updated.
