Incorrect statements in createWindowsDevkit2017.sh

While investigating JDK-8254252 that seems to have been triggered by the Windows AArch64 Support change (JDK-8248238), I found this part which looks incorrect to me:

-cp $DEVKIT_ROOT/VC/redist/x64/$MSVCP_DLL $DEVKIT_ROOT/VC/bin/x64
+cp $DEVKIT_ROOT/VC/redist/x64/$MSVCR_DLL $DEVKIT_ROOT/VC/bin/x64
+cp $DEVKIT_ROOT/VC/redist/arm64/$MSVCP_DLL $DEVKIT_ROOT/VC/bin/arm64
+cp $DEVKIT_ROOT/VC/redist/arm64/$MSVCP_DLL $DEVKIT_ROOT/VC/bin/arm64
https://openjdk.github.io/cr/?repo=jdk&pr=212&range=11#udiff-6

Why is MSVCP_DLL changed to MSVCR_DLL for x86? And why are the two arm64 specific lines duplicates?
The corresponding change to createWindowsDevkit2019.sh looks good:
