No, it is not. From composer.json:

=======================
{
	"name": "typo3/cms/install",
	"type": "typo3-cms-framework",
	"description": "TYPO3 Core",
	"homepage": "http://typo3.org",
	"license": ["GPL-2.0+"],
	"version": "6.2.0",

	"require": {
		"typo3/cms/core": "*",
		"typo3/cms/fluid": "*",
		"typo3/cms/extbase": "*"
	},
	"replace": {
		"install": "*"
	}
}
=======================

Core and extbase are resolved from 'typo3/cms/XXX' to 'XXX' because they 
are loaded before install but 'typo3/cms/fluid' is not resolved to fluid 
because it is not loaded yet. So the dependency stays as is 
(getPackageKeyFromComposerName throws an exception and forces the use of 
'typo3/cms/fluid'). When later code looks up for 'typo3/cms/fluid' in the 
list of packages, it cannot find it because it is not resolved to 'fluid'.
