The YouTube video shows indeed an unknown but very valid method to integrate these applications and their creations ! The Extended Meta File (EMF, and its former WMF) are vector based formats, which are capable of picking up pretty much what many other drawing applications can create.

But there are limits !
Especially textual aspects can be cumbersome.

First of all: drawing files are (like many others, except PDF) dependent of the availability of a certain font. So if the text is set in a font which is unavailable on a system, a substitute font will be used. This can cause characters not only to look totally different, but also to break differently, due to non-matching character widths.

If the exact font is available, then characters will look okay but the whole text might still break differently, due to subtle differences in character spacing and hyphenation. Apps like PowerPoint aren't as sophisticated in i.e. spacing and hyphenating as Adobe Illustrator is...

And there are many other features missing in the WMF/EMF formats, which will cause other aspects also to get messed up. E.g. fill and line effects (like gradients, patterns, and dashes), and any other complex constructions (like compounds, masks, blends, etc.) might not be understood by the interpreting application, or even be implemented in the EMF format.

The best way to overcome any (typo)graphical differences, is to restrict yourself to simple designs, or to Expand as many complex elements as possible, so the drawing consists solely of paths with plain fills. Of course, expanding will render text to lose its textual nature, so you can't change the text and typography anymore.

Another issue which might also appear, is a difference in drawing with precision, because EMF/WMF or the interpreting application only work with integer point/pixel sizes – not fractional ones.
