What is the definition of transversality used in this context?

Now, I've been reading V.I. Arnol'd, Characteristic Class Entering in Quantization Conditions and I'm stuck on page 10. Here is the link

He tolds that

$uM^{(n)}$ is such that its tangential mapping $\tau$ is transversal to every $\Lambda^k(n) \hookrightarrow \Lambda(n), k=1,2,\dots$.

However, I think the dimension of $\tau^* T_x (uM^{(n)}) + T_{\tau(x)} \Lambda^k(n)$ is strictly less than $T_{\tau(x)} \Lambda(n)$ for some large $k$.

How do I interpret this statement correctly?

EDIT: In here, $uM^{(n)}$ is an $n$-dimensional Lagrangian manifold. $\Lambda(n)$ is an algebraic variety, called Lagrangian grassmanian, which is a collection of all Lagrangian subspaces of $\mathbb{R}^{2n}$. $\Lambda^k(n)$ is a manifold of Lagrangian subspaces of $\mathbb{R}^{2n}$ whose intersection with standard position subspace($q=0$) is $k$-dimensional and it is $\dfrac{k(k+1)}{2}$ codimensional submanifold of $\Lambda(n)$. $\tau$ is a tagential mapping from $M^{(n)}$ to $\Lambda(n)$; mapping a point $x$ to the tangent space $T_xM$ of $M$ at the point, and it is well-defined since $M$ is a Lagrangian manifold in $\mathbb{R}^{2n}$.

The context is, he tried to assert that $uM^{(n)}$ is in general position from showing that each element of $\tau(uM^{(n)})$ is transverse to $\overline{\Lambda^1(n)}$.
